Electric bike accessories range from storage solutions to safety gear, and the right ones turn a good ride into a great one. My top pick overall is the LISEN Bike Phone Holder, which balances easy installation, grip strength, and price better than anything else in this lineup. The Lamicall Lockable Mount is the stronger choice if you want one-hand operation and maximum phone security, while the JXFUKAL Rear Rack Bag with Rain Cover stands out for commuters who need weatherproof storage on a budget. The main tradeoff you will face in this category is between convenience and security on mounts, and between capacity and weight on bags. Continue reading for the full breakdown of all eight accessories and who each one suits best.

Key Takeaways
- Phone mounts showed the widest quality spread: the LISEN wins on ease of installation, while the Lamicall justifies its higher price with a lockable, one-hand-operated clamp that cheaper mounts simply do not offer.
- The two JXFUKAL bags serve different riders — the hard shell version suits heavy cargo and e-bike touring, while the softer 7L–12L rain-cover model is the smarter pick for daily commuting at a lower price.
- The ROCKBROS frame bag is the only accessory that combines storage and phone viewing in one unit, making it the best space-saver for riders with crowded handlebars.
- The 130dB horn delivers the biggest safety-per-dollar return of any product here, but it is a single-purpose device with no weather-sealing claims.
- The Pro Bike Speaker is the one purely recreational pick — excellent battery life and waterproofing, but it competes for handlebar space with mounts and should only come after storage and safety needs are covered.

More Details on Our Top Picks
JXFUKAL Bike Bags for Bicycle Rear Rack – 9.5L Hard Shell Ebike Bag
Among storage-focused picks in this lineup, this hard shell rack bag stands out for protecting cargo that soft bags can’t. The EVA shell and PU coating mean a laptop, groceries, or spare battery survive rain and rough roads without the sag-and-soak problem typical of fabric panniers. Compared with the JXFUKAL 7L–12L soft rack bag elsewhere in this roundup, this model trades a bit of flexible packing space for structure and weatherproofing. Multiple compartments keep tools separate from snacks, and reflective trim adds visibility that a phone mount like the LISEN holder simply doesn’t address. The shoulder strap makes it usable off the bike too.
The tradeoffs are real, though: the listing’s rain cover details are inconsistent, and 9.5L fills fast on touring days — long-distance riders should look at the 17L or 40L versions instead.
Pros:- Hard EVA shell protects contents better than soft panniers
- Waterproof construction with PU coating
- Reflective elements improve night-riding visibility
- Multiple compartments keep gear organized
Cons:- 9.5L capacity is tight for long trips
- Rain cover availability is inconsistent with the product description
Best for: Commuters and errand riders who carry electronics or fragile cargo and want weatherproof, organized rack storage
Not ideal for: Bikepackers and touring riders needing multi-day capacity — 9.5L runs out quickly, and a bar bag like the ROCKBROS tube pouch supplements rather than replaces it
- Capacity:9.5L
- Dimensions:15.35 x 6.89 x 7.87 inches
- Material:EVA with PU coating
- Waterproofing:Waterproof shell
- Safety:Reflective elements
- Carrying:Shoulder strap and handle
- Mounting:Fits most rear racks
Our verdict“Buy this if you want rack storage that shields cargo from weather and impacts; skip it if you need touring-level capacity.”
Electric Bike Horn 130dB Loud Bicycle Horn for Handlebar Mounting
Most accessories in this roundup make rides more convenient; this one can prevent a collision. A 130dB electric horn cuts through traffic noise far better than a squeeze bulb, and the one-button trigger lets you sound it without shifting your grip — something you can’t do while fumbling with a phone in the LISEN or Lamicall mounts. Tool-free installation via elastic bands means it mounts in seconds, and the IPX4-rated ABS housing shrugs off rain.
Compared with the Pro Bike Speaker in this lineup, which entertains but doesn’t alert, this is the accessory I’d mount first on an e-bike that travels at 20+ mph where reaction time matters. The tradeoffs: the CR2032 batteries will need replacing eventually, and the mount only fits handlebars from 22.2 to 32mm — oversize e-bike bars may rule it out.
Pros:- 130dB output is loud enough for busy traffic
- Tool-free installation with elastic bands
- IPX4 waterproof and durable ABS housing
- Long battery life of up to 200 days
Cons:- Handlebar fit limited to 22.2–32mm diameter
- Replaceable batteries add ongoing maintenance
Best for: Urban e-bike commuters who ride in mixed traffic and need to alert distracted pedestrians and drivers
Not ideal for: Riders with oversize handlebars above 32mm or those who dislike startling pedestrians with a very loud horn
- Volume:130dB
- Handlebar Range:22.2–32mm
- Battery:2 x CR2032 (replaceable)
- Battery Life:Up to 200 days / 5,000 rings
- Waterproof Rating:IPX4
- Material:ABS
Our verdict“This is the cheapest collision-avoidance tool you can bolt onto an e-bike, provided your handlebars fall within its diameter range.”
LISEN Bike Phone Holder – Easy Install Handlebar Mount, Black
For riders who want nav on a budget, this silicone mount delivers the core job — holding a phone steady — at the lowest complexity of the three phone mounts here. The stretchy silicone design grips phones from 4.7 to 6.8 inches and absorbs vibration better than rigid plastic, so screens don’t rattle on chip-seal roads. Unlike the Lamicall lockable mount, there’s no mechanism to jam or misalign; installation is a matter of stretching it over the bar.
That simplicity cuts both ways: the Lamicall’s one-hand lock release is genuinely faster mid-ride, and this LISEN mount has no stated weather resistance, so rain riders should weigh the weather-resistant alternative from the same roundup. Phones thicker than 20mm (chunky cases included) won’t fit, and bars outside 0.6–1.57 inches are out. For fair-weather commuters, those limits rarely matter.
Pros:- Silicone construction absorbs vibration and won’t scratch the phone
- Tool-free installation takes under a minute
- Secure grip survives bumpy and high-speed rides
- Works on bikes, eBikes, motorcycles, and scooters
Cons:- No stated waterproofing for rainy rides
- Won’t fit phones or cases thicker than 20mm
Best for: Budget-conscious commuters with standard-sized phones who ride in dry conditions
Not ideal for: Riders who use thick protective cases or ride in frequent rain — the 20mm thickness limit and lack of weatherproofing are dealbreakers
- Phone Compatibility:4.7″–6.8″ smartphones up to 20mm thick
- Handlebar Diameter:0.6–1.57 inches
- Material:Silicone
- Installation:Tool-free
- Shock Protection:Shockproof silicone
- Warranty:12 months
Our verdict“The simplest, most affordable way to mount a standard phone — just confirm your case thickness and skip it if you ride wet.”
Lamicall Bike Phone Holder Motorcycle Mount – One-Hand Operation, Lockable
This is the mount for riders who interact with their phone constantly — checking routes, skipping tracks, answering calls at stops. The red switch lock and corner clamps hold the phone with more mechanical certainty than the LISEN’s stretchy silicone, and the one-hand release is faster than pulling a phone out of the LISEN or rotating the universal mount’s 360-degree joint mid-ride. Adjustable orientation suits both portrait navigation and landscape video.
Those clamps come with a learning curve, though: pulling the arms incorrectly can jam the gearing, a complaint the LISEN’s simpler design never invites. Like its rivals, it demands a handlebar measurement before purchase (0.59–1.57 inches), and it won’t hold phones thicker than 0.59 inches. Compared with the weather-resistant budget mount in this roundup, the Lamicall favors grip and convenience over weather sealing.
Pros:- Lockable corner clamps keep the phone secure on rough roads
- True one-hand operation for quick mount and removal
- Adjustable horizontal or vertical orientation
- Silicone padding prevents scratches and vibration damage
Cons:- Arms can jam if operated incorrectly
- Requires handlebar measurement before purchase
- 0.59-inch phone thickness limit excludes some rugged cases
Best for: Daily riders and delivery riders who mount and remove their phone dozens of times a day and want one-hand operation
Not ideal for: Set-and-forget riders on tight budgets — the LISEN covers the basics for less, without a lock mechanism that can jam
- Phone Compatibility:4.7″–6.8″ phones up to 0.59 inches thick
- Handlebar Diameter:0.59–1.57 inches (15–40mm)
- Material:Plastic with silicone pads
- Locking Mechanism:Red switch lock
- Orientation:Adjustable horizontal/vertical
- Installation:Tool-free
Our verdict“Pay the premium for one-hand convenience and a locking grip if you touch your phone constantly; otherwise the LISEN covers the basics for less.”
Bike Phone Holder Mount for Handlebar, Weather-Resistant Smartphone Mount
When the forecast is the deciding factor, this mount pulls ahead of both the LISEN and the Lamicall in this lineup. Its weather-resistant construction is the only one of the three built for sustained wet riding, and the anti-vibration grip keeps phones steady on gravel and potholes where cheaper mounts rattle. The 360-degree rotation is smoother to adjust on the move than the Lamicall’s clamps, and it covers the widest device range at 4.5 to 6.8 inches.
The catch is fit: at 0.61–1.13 inches of handlebar compatibility, it actually covers a narrower bar range than either rival, and its 3.86-ounce bulk can look oversized on slim city bars. Installation takes some fiddling to dial in perfectly, where the LISEN stretches on in seconds. Riders who rarely see rain should weigh whether weather sealing justifies that extra fuss.
Pros:- Weather-resistant build handles rain and changing conditions
- Anti-vibration grip stays secure on rugged terrain
- 360-degree rotation for flexible viewing angles
- Fits the widest phone range at 4.5–6.8 inches
Cons:- Narrower handlebar range than rival mounts (0.61–1.13 inches)
- Bulky footprint on smaller handlebars
- Installation requires adjustment for a perfect fit
Best for: All-season commuters and gravel riders who need a phone visible in rain and rough terrain
Not ideal for: Riders with larger-diameter handlebars above 1.13 inches or anyone wanting a minimal, lightweight cockpit
- Phone Compatibility:4.5″–6.8″ smartphones
- Handlebar Diameter:0.61–1.13 inches
- Material:ABS, plastic, rubber
- Weather Resistance:Water resistant
- Rotation:360 degrees
- Weight:3.86 ounces
- Dimensions:2.75 x 1.75 x 4.78 inches
Our verdict“Choose this over the LISEN and Lamicall if you ride in bad weather — just verify your handlebar diameter first.”
ROCKBROS Bike/Bicycle Phone Front Frame Bag, Waterproof, Tube Cycling Pouch
For riders who want phone access and storage in one purchase, this bag does the work of two accessories for the price of one. The high-sensitivity TPU touchscreen window lets you check navigation without stopping, which a bare handlebar mount like the Lamicall Bike Phone Holder also achieves — but the ROCKBROS adds room for keys, tools, and snacks underneath. The tradeoff is positioning: your phone sits on the top tube rather than at eye level, so glancing at maps means looking down. Compared with the JXFUKAL Rear Rack Bag, storage here is far smaller, but everything stays within arm’s reach while riding. Fit is the real limitation — oversized e-bike top tubes can defeat the three-strap mounting system entirely.
Pros:- Combines phone mounting and storage in one affordable accessory
- High-sensitivity TPU window allows touchscreen use while riding
- Sealed double zippers and water-resistant fabric protect contents in rain
- Reflective tapes add nighttime visibility at no extra cost
Cons:- Not compatible with oversized e-bike top tubes or large frames
- Touch ID doesn’t work through the screen cover and thick phone cases may not fit
Best for: Budget-conscious commuters and casual riders who want navigation access plus small-item storage without buying a separate phone mount
Not ideal for: Riders with thick-cased phones or full-suspension e-bikes with oversized frames — the fit and touchscreen compatibility become unreliable
- Capacity:Large space for phone, keys, repair kits
- Phone Compatibility:Up to 7 inches with slim cases
- Material:Carbon fiber texture fabric
- Water Resistance:Water resistant with sealed double zippers
- Installation:3 straps with hook and loop fasteners
- Safety Features:Reflective tapes, earphone hole
Our verdict“A smart two-in-one pick for casual riders who value convenience and low cost over premium build or eye-level phone viewing.”
JXFUKAL Rear Bike Rack Bag with Rain Cover, 7L/9L/10L/12L Ebike Bag
Once your storage needs outgrow the ROCKBROS frame bag, this rear rack bag is the logical next step — its 7L to 12L capacity options swallow a laptop, lunch, and a lock, none of which fit in a top-tube pouch. The PU leather and polyester construction reads as more polished than typical nylon rack bags, and the multiple compartments keep work gear separated from tools. Riders who need serious hauling should still compare it against the JXFUKAL Hard Shell 40L, which offers far more capacity and rigid structure for touring. This soft-sided version wins on weight and everyday practicality, but the marketing overstates completeness: despite the product title, the rain cover is not included, and there’s no rear belt for mounting a taillight — small gaps that add cost and hassle after purchase.
Pros:- Four capacity options let you match bag size to your actual cargo needs
- Multiple compartments keep gear organized and separated
- PU leather and polyester build resists water and daily wear better than basic nylon
- Reflective strips improve visibility on dark commutes
Cons:- Rain cover is not actually included despite the product title
- No rear belt for attaching a taillight, limiting rear lighting options
- Capacity is too small for bulky touring or grocery loads
Best for: E-bike commuters and weekend riders who need organized, moderate cargo capacity for daily trips rather than full touring loads
Not ideal for: Long-distance tourers or shoppers carrying bulky items — capacity maxes out at 12L, and the hard shell 40L model fits that job better
- Capacity:7L / 9L / 10L / 12L
- Dimensions:12 x 6.7 x 5.5 inches
- Material:PU leather & polyester
- Water Resistance:Water-resistant shell (rain cover sold separately)
- Safety Features:Reflective strips
- Mounting:Velcro straps for rear rack attachment
- Organization:Multiple compartments
Our verdict“The right choice for organized commuters who want stylish, moderate-capacity storage — just budget for a separately purchased rain cover.”
Pro Bike Speaker with Handlebar Mount, Bluetooth 5.4, IPX7 Waterproof, 10W Bass, 15-24H Playtime
Not every accessory is about hauling or navigating — this speaker exists for riders who consider music part of the ride. The IPX7 waterproof rating is the standout here, surviving rain and splashes that would kill a generic portable speaker strapped to handlebars, and the stable mount keeps it planted on rough roads. Pairing it with the 130dB Electric Bike Horn from this roundup makes sense: the speaker handles entertainment while the horn covers safety, so you’re not relying on audio cues through music. Compared with stuffing earbuds in, an open speaker keeps your ears on traffic. The catch is opacity — the listing offers no speaker dimensions, weight, or detailed audio specs, so audiophiles buying on sound quality alone are gambling. Bluetooth-only connectivity also rules out any non-Bluetooth audio source.
Pros:- IPX7 waterproofing survives rain and splashes without a protective case
- Up to 24 hours of playtime covers a full week of commutes on one charge
- Stable handlebar mount stays secure over rough terrain
- Bluetooth 5.4 maintains a reliable connection on the move
Cons:- No published speaker size, weight, or audio-quality details
- Bluetooth-only design excludes non-Bluetooth devices
- Adds handlebar clutter that competes with phone mounts and lights for space
Best for: Leisure riders and commuters who want music or podcasts on the move without blocking traffic sounds with earbuds
Not ideal for: Audio enthusiasts who care about sound fidelity — the thin spec sheet means no verified audio-quality claims before buying
- Bluetooth Version:V5.4
- Waterproof Rating:IPX7
- Power Output:10W bass
- Playtime:15–24 hours
- Shell Material:Waterproof silicone
- Mounting:Handlebar mount
- Compatibility:Bicycles, motorcycles, electric scooters
Our verdict“A fun, weatherproof upgrade for riders who treat music as essential gear — skip it if handlebar real estate or audio fidelity is your priority.”
How We Picked
I evaluated these accessories against criteria that matter most to e-bike riders: ease of installation, durability in real weather, compatibility with e-bike geometry (heavier frames, wider handlebars, throttle and display clutter), and value relative to alternatives. Because e-bikes travel faster and farther than pedal bikes, I weighted vibration resistance on phone mounts and water resistance on bags and speakers more heavily than a standard bicycle roundup would.
The ranking order reflects a practical priority: safety and navigation come first, which is why a phone mount sits at the top and the horn ranks high despite its low price. Storage solutions follow, ranked by versatility and weather protection. The speaker closes the list because it enhances rides but does not protect gear, phone, or rider. Within each category, I compared directly — for example, the three phone mounts were judged against each other on clamping mechanism, one-hand usability, and shock absorption, which is what separated the LISEN and Lamicall from the generic mount.
Factors to Consider When Choosing Electric Bike Accessories
Shopping for electric bike accessories involves a few decisions that go beyond picking individual products. These are the factors that shaped my rankings and the mistakes I see buyers make most often.Handlebar Real Estate Is Finite
E-bike handlebars are more crowded than most riders expect: displays, throttle levers, brake levers, bell, and light mounts all compete for space. Before buying any accessory, map out where it will actually fit — this is the single most common return reason for mounts and speakers. A frame bag like the ROCKBROS can be the smarter solution if your bars are already full, since it uses otherwise dead space on the top tube. Riders who plan to mount both a phone holder and a speaker should measure spacing first, because two clamps on adjacent bar sections can interfere with braking hand positions. Priority order should be safety devices, then navigation, then entertainment.
Vibration Resistance Matters More on E-Bikes
Because e-bikes carry motor and road vibration at higher speeds, a phone mount that works fine on a casual pedal bike can rattle loose within weeks. Locking mechanisms — like the Lamicall’s clamp lock — exist specifically for this problem, and the price premium buys real security rather than a gimmick. Cheaper silicone-strap mounts may hold at first but stretch and fatigue over time, which is a costly failure mode when a phone is involved. If you ride on rough roads or gravel regularly, treat a lockable mount as the default rather than the upgrade. Also check that the mount’s damping pads touch your phone case, not just the bare phone, since most riders use cases.
Water Protection: Ratings vs. Rain Covers
There are two approaches to weather protection, and they suit different riders. Hard shells and IPX ratings (like the Pro Bike Speaker’s IPX7) offer permanent protection with no action required. Removable rain covers, like the one on the JXFUKAL rack bag, are cheaper and often more breathable but depend on you actually deploying them before the weather turns. Commuters who get caught in unpredictable rain should lean toward built-in waterproofing; fair-weather riders can save money with a cover. One common mistake is assuming water-resistant means submersible — most bags in this category resist rain but fail if left outside in a downpour overnight.
Capacity and Weight Tradeoffs on Storage
Bigger is not automatically better for rack bags. A 40L hard shell bag swallows touring gear but adds noticeable weight high on the rack, which affects handling — particularly when combined with a rear-mounted battery. Smaller 7L–10L bags hold a lock, tools, and a change of clothes without changing how the bike feels. Think about what you actually carry daily rather than maximum capacity, because underfilled large bags develop sag and flap at speed. Hard shells protect contents from crush and impact but cost more and cannot be compressed when empty; soft bags fold flatter but offer less structure.
Buy for the Battery Era
E-bike-specific accessories differ from standard bike gear in small but meaningful ways. Charging access matters — a bag or frame pouch that lets you route a cable to a power bank can extend GPS tracking on long rides. Speakers with 15+ hour battery life, like the Pro Bike Speaker, exist because e-bike riders cover distances where shorter batteries die mid-ride. Weight capacity also matters: rear racks on e-bikes often support more load, which is why the larger JXFUKAL hard shell is viable on an e-bike where it might overwhelm a lightweight road bike. Always check whether an accessory assumes a rack or battery placement you do not have.
When to Pay More and When to Save
Spend more on anything that protects an expensive item or your body: lockable phone mounts and loud horns deliver outsized returns relative to their price. Save on items where the cheap version does the core job — a basic horn or a simple rain-cover bag performs 90% of the premium alternative’s function. The middle zone is where most wasted money sits: mid-priced mounts without locking mechanisms, or mid-capacity bags that are neither light nor spacious. If budget forces a choice, buy the phone mount first, then storage, then the speaker last. Accessories are cumulative purchases, and there is no penalty for adding them over months as needs become clear.
Frequently Asked Questions
Do I need a lockable phone mount, or is a standard clamp enough?
It depends on your riding surface and phone value. Standard clamps like the LISEN handle smooth roads and moderate speeds well, and their tool-free installation makes them convenient for casual riders. Lockable mounts such as the Lamicall earn their premium when you ride on potholed streets, gravel, or at Class 3 e-bike speeds above 20 mph, where sustained vibration is what loosens cheaper mechanisms over weeks rather than days. A lock also enables true one-hand operation, which matters if you check navigation frequently at stops. If replacing your phone would strain your budget, the lockable mount is cheap insurance; if you ride gently on maintained paths, the standard mount is the better value.
Should I get a frame bag or a rear rack bag for storage?
They solve different problems, and many riders eventually own both. A frame bag like the ROCKBROS sits in front of you, keeps small items reachable without dismounting, and doubles as a phone platform — but capacity is limited to snacks, tools, and a compact layer. A rear rack bag carries real loads: locks, groceries, a change of clothes, and rain gear, with the JXFUKAL options ranging from 7L commuter sizes to 40L touring capacity. If your e-bike has a rack installed, the rack bag is the more versatile first purchase. If your bike lacks a rack or you only need quick-access items, start with the frame bag and skip the installation hassle entirely.
Is a 130dB horn actually necessary, or is a bell enough?
A bell works for alerting pedestrians on shared paths at close range, but it fails in traffic where drivers have windows up and music playing. A 130dB horn cuts through that ambient noise, which is exactly the situation where e-bike riders are most vulnerable — moving at speeds cars do not expect from bicycles. The tradeoff is that horns of this volume can startle pedestrians badly on quiet paths, so you still want a bell or voice warning for mixed-use trails. Placement also matters: it needs handlebar space within thumb reach without blocking brake levers. For urban commuters, the horn is one of the cheapest safety upgrades available; for park and trail riders, a bell remains the politer and adequate choice.
Can I mount a phone holder and a speaker on the same handlebar?
Usually yes, but it requires planning. Most e-bike handlebars have room for two clamp devices if you position the speaker toward the stem center and the phone mount on one side, keeping both clear of brake and shift levers. Check the clamp diameter ranges on both products against your bar size, since some e-bikes use oversize or riser bars that narrower clamps cannot grip. Weight is a minor factor but worth noting — a speaker plus phone plus case adds noticeable steering inertia on technical rides. If space runs out, the ROCKBROS frame bag becomes the workaround, freeing the handlebar by handling phone duty from the top tube.
What size rack bag do I actually need for commuting?
Most commuters find 7L to 10L covers a lock, tools, pump, and a layer or lunch, which is why the JXFUKAL soft bag in those sizes is my value pick. The 12L option suits riders who carry a change of clothes or shoes regularly. Stepping up to the 40L hard shell only makes sense for touring, shopping runs, or riders who routinely haul cargo, because a half-empty large bag sags, flaps at speed, and raises the center of gravity near the battery. Measure your rack’s dimensions before ordering, since e-bike racks vary in width and some oversized bags overhang the edges. A practical test: gather what you normally carry, put it in a grocery bag, and compare — that volume maps almost directly to the bag size you need.
Conclusion
The right accessory depends on what your rides are missing. For best overall, the LISEN Bike Phone Holder delivers the best balance of price, grip, and tool-free installation for the widest range of riders. The best value pick is the JXFUKAL Rear Rack Bag with Rain Cover, which solves commuter storage for less than the cost of most premium alternatives. For best premium, the Lamicall Lockable Mount justifies its higher price with one-hand operation and vibration-proof security for expensive phones. Beginners get the most from the Electric Bike Horn — the cheapest, simplest safety upgrade with immediate benefit. For specific needs: the ROCKBROS Frame Bag for crowded handlebars, the JXFUKAL 40L Hard Shell for cargo and touring, and the Pro Bike Speaker for riders who want music on long-distance rides. Whichever you choose, prioritize safety and navigation first, then build your setup from there.
