The models in detail
This page is for riders who want a simple screen for speed and distance, either on a regular bike or on an e-bike whose built-in display shows too little. We picked six models from Amazon.com product listings checked on October 10, 2026, and compared them using what each listing states. We did not mount or ride with any of them, so every figure here is a manufacturer or seller claim.

CatEye Velo 7
Bike computer4,4/5 from 5541 Amazon customer ratings (as of October 10, 2026)
The CatEye Velo 7 does the core job of a bike computer: current, max and average speed, total and trip distance, elapsed time, a pace arrow and the clock. Auto stop/start pauses time and average speed when you halt at a light. Its strongest point on an e-bike site is the wired sensor. Two wireless models on this page carry a seller warning about some electric-assist bikes, and a cable sidesteps that question, at the cost of routing it from the fork to the handlebar. The battery is rated to last up to three years, the longest claim here. What the listing leaves out matters too: there is no water-resistance rating and no mounting detail, so check your bar and fork before ordering. It has no GPS, cadence or heart-rate data. Customers rate it 4.4 out of 5 across 5,541 reviews, tied for the best score on this page.
Pros, cons and specs
Pros
Shows current, max, and average speed, total and trip distance, elapsed time, a pace arrow, and the clock.
Automatically pauses time and average speed when you stop.
Battery rated to last up to three years, according to the listing.
Cons
Wired sensor, so a cable has to be routed from the fork to the handlebar.
No GPS, cadence, or heart-rate data; speed and distance only.
Water resistance and mounting details are not given on this listing.
Best for: Beginner riders who want a simple, long-lasting speedometer and odometer.
Skip it if you want GPS tracking, navigation, or a wireless sensor.

FunctionsCurrent, max and average speed; total and trip distance; elapsed time; pace arrow; clock; auto stop/start
This SY wireless computer, sold under a YS label on the listing, measures speed, distance and riding time on a backlit LCD. It wakes up when it senses vibration, and any button press turns the backlight on between 18:00 and 06:00, which helps on evening commutes. Tire size is adjustable, so you can match it to your wheel. The catch for this site is clear: the listing warns it may not be compatible with some electric-assist bicycles, so a hub motor or wiring near the sensor could disturb readings. It is sold as waterproof with no rating, and the seller calls a slight rattle from the unit normal. At 3.8 out of 5 over 5,385 reviews, it scores below the CatEye models. Compared with the Velo 7, you lose the long battery claim and gain a cable-free install. Treat it as a regular-bike option first.

FunctionsSpeed, distance, riding time; auto wake-up
The CYCPLUS G1 uses GPS to track speed, distance, ride time, total mileage and current altitude, so nothing has to be fitted near the wheel or the hub motor. That makes it the easiest model here to add to an e-bike without worrying about sensor placement. The 1200 mAh battery is rated for more than 55 hours, it weighs 70 g according to the listing, and the 2.0 in FSTN screen has an auto backlight and tempered glass. It carries an IPX6 rating, the clearest water figure on this page. The limits come from the brand's own comparison table: no ANT+ sensors, no app connection, no ride export and no navigation. The screen is also the smallest in the CYCPLUS lineup. It sleeps after 10 minutes of inactivity and shows your last ride when turned back on. Customers give it 4.2 out of 5 over 4,267 reviews.

FunctionsRide time, distance, total time, total mileage, clock, current altitude
This unbranded wireless computer shows speed, distance and riding time on a large LCD, with a backlight that comes on when you press a button between 18:00 and 06:00. A wireless sensor and magnet spare you the cable run that the Velo 7 requires, and you can enter your tire size for better accuracy. Two buttons reach every function. It has a lot in common with the SY unit above, including the same weak points. The seller warns it may not suit some electric-assist bikes, the listing gives no water-resistance rating and no battery life, and a slight rattle is described as normal. There is no GPS and no app. If your e-bike already has a display, this adds little. It holds 3.8 out of 5 across 2,515 reviews, level with the SY and below every CatEye on this page.
Pros, cons and specs
Pros
The large LCD shows speed, distance and riding time.
A wireless sensor and magnet avoid running a cable along the fork.
The backlight comes on when a button is pressed between 18:00 and 06:00.
Two buttons access all functions, and the tire size can be customized for accuracy.
Cons
The seller warns it may not be compatible with some electric-assist bikes.
No GPS, no app and no water-resistance rating or battery life are given.
The listing says a slight rattle from the unit is normal.
Best for: Riders of standard bikes who just want basic speed and distance readings.
Skip it if your e-bike already has a display or you want GPS tracking.
The CatEye Padrone Wireless is built around an oversized display that you operate by pressing the base of the unit, a system CatEye calls ClickTec, so there are no menus to scroll. For riders who glance down at speed in traffic, that big screen is the main reason to choose it over the Velo 7. The wireless speed sensor works on the front wheel only and has a 70 cm range with no pairing step, which suits e-bikes with a rear hub motor as long as your front fork has room for it. The FlexTight bracket goes on without tools. You get current, max and average speed, total and trip distance, elapsed time, a clock, a programmable odometer and auto start/stop. The listing does not give battery life, and there is no GPS, navigation or heart rate. Customers rate it 4.2 out of 5 over 2,464 reviews.
Pros, cons and specs
Pros
Oversized display operated by pressing the base of the unit (ClickTec), with no menus to navigate.
Wireless front-wheel speed sensor with a 70 cm range and no pairing required.
Tool-free FlexTight bracket and automatic start/stop.
Programmable odometer, per the title.
Cons
No GPS, navigation, or heart rate, as the listing states.
Sensor works on the front wheel only, and battery life is not given on this listing.
Best for: Riders who want a large, easy-to-read speedometer without GPS complexity.
Skip it if you want ride recording, navigation, or smartphone sync.

FunctionsCurrent, max and average speed; total and trip distance; elapsed time; clock; programmable odometer; auto start/stop
The CatEye Velo Wireless keeps the Velo 7 feature set and adds calorie estimates and a programmable odometer, so your total mileage survives a battery change. Auto stop/start pauses time and average speed at red lights. The sensor and wheel magnet are wireless, and CatEye says it works on 27.5 and 29-inch wheels. A zip-tie bracket holds it on the handlebar. Battery life is about 1 year on a CR2032 cell, based on 1 hr of riding per day, which is shorter than the wired Velo 7. The brand table lists water resistance as IXP8, most likely a typo for IPX8, so treat that figure with care. Unlike the SY and unbranded units, the listing carries no warning about electric-assist bikes, though it does not confirm e-bike use either. It has no GPS, cadence or heart-rate data and shares the top score here, 4.4 out of 5 over 2,350 reviews.

FunctionsCurrent, max and average speed; total and trip distance; elapsed time; calories; pace arrow; clock; programmable odometer; auto stop/start
On an e-bike, a wired sensor is the safer bet when the listing warns about electric-assist bikes. Two wireless units on this page, the SY and the unbranded LCD model, carry exactly that warning from their sellers, which suggests the motor or its wiring can disturb the signal. The wired CatEye Velo 7 avoids the question but asks you to run a cable along the fork. The CatEye Padrone and Velo Wireless carry no such warning, yet they do not confirm e-bike use either. Check where your motor sits before choosing.
GPS or wheel magnet
Choose GPS if you do not want anything mounted near the wheel. The CYCPLUS G1 is the only GPS model here and reads speed, distance and altitude from satellites, so a hub motor cannot get in the way. The trade-off is that GPS units need charging, while magnet computers run on coin cells for months or years. The G1 also has no app and no ride export, so it is still a speedometer, not a training device. The five other models all rely on a wheel magnet and sensor.
Screen size and backlight
A larger, backlit screen is what makes a bike computer usable at a glance. The Padrone has the oversized display on this page and drops menus entirely. The SY and unbranded LCD units light up with a button press between 18:00 and 06:00, which helps on dark commutes. The G1 has an auto backlight on a 2.0 in screen, the smallest in its brand's lineup. The listings for the Velo 7 and Velo Wireless do not describe a backlight, so plan on daylight use unless you confirm otherwise.
Battery life claims
Coin-cell computers last far longer between battery swaps than a GPS unit lasts between charges. The Velo 7 claims up to three years, the Velo Wireless about 1 year on a CR2032 at 1 hr per day, and the G1 more than 55 hours per charge. The SY, the unbranded unit and the Padrone listings give no battery figure at all. All of these are claims from the listings. A programmable odometer, found on the Padrone and Velo Wireless, keeps your total mileage when the cell is replaced.
Water resistance
Only one model here has a clear water rating, the CYCPLUS G1 at IPX6. The Velo Wireless brand table lists IXP8, likely a typo, and the SY and unbranded computers are described as waterproof with no rating given. The Velo 7 and Padrone listings say nothing about water. If you commute in rain, favor a stated rating and avoid leaving any unit on the bike in a downpour when you park. A missing rating does not mean the device fails in rain; it means the listing does not promise anything.
Does your e-bike already show this?
Many e-bikes already display speed and distance, so check your own display before buying a second screen. A separate computer earns its place when your built-in display is small, hard to read in sun, or missing features like average speed, a trip counter or altitude. The Padrone's oversized screen and the G1's altitude reading fill those gaps best. If your bike has no display at all, any model here adds basic numbers, but read the e-bike warnings on the cheaper wireless units first.
Skip it if…
you want turn-by-turn navigation, since no model on this page offers it.
you need heart-rate, cadence or power data for training.
you expect to sync rides to a phone app, which the G1 does not support and the others lack entirely.
your e-bike display already shows speed, trip distance and average speed clearly.
you ride a hub-motor e-bike and only consider the SY or unbranded wireless units, whose sellers flag possible e-bike issues.
FAQ
What is the best bike computer for an e-bike?
The CatEye Velo 7 is our pick because its wired sensor avoids the e-bike interference warnings that two wireless models on this page carry. It covers speed, distance, time and a pace arrow with a battery rated up to three years. If you would rather mount nothing near the wheel, the CYCPLUS G1 uses GPS instead.
Do wireless bike computers work on electric bikes?
Some do, but two sellers on this page warn that their wireless units may not be compatible with some electric-assist bicycles. The motor and its wiring can sit close to the sensor. The CatEye wireless models carry no such warning, though they do not confirm e-bike use. A wired or GPS computer removes the doubt.
Is a GPS bike computer better than a wired one?
A GPS bike computer is better if you want altitude and no wheel sensor, while a wired one is better for battery life and simplicity. The CYCPLUS G1 claims more than 55 hours per charge and shows current altitude. The CatEye Velo 7 claims up to three years on one battery but reads only speed, distance and time.
Which bike computer has the biggest screen?
The CatEye Padrone Wireless has the oversized display on this page, and you change screens by pressing the base of the unit rather than using menus. The unbranded wireless model also advertises a large LCD. The CYCPLUS G1 has a 2.0 in screen, which the brand itself lists as the smallest in its lineup.
Can a bike computer show my e-bike's battery level?
No, none of these six models reads your e-bike battery. They measure speed and distance from a wheel magnet or GPS, and none connects to a motor system. Battery level, assist mode and range estimates stay on your e-bike's own display. Use an add-on computer for larger speed readouts, trip counters or altitude, not for motor data.
How do I set up a wheel-sensor bike computer correctly?
Enter your exact tire size, then line the magnet up with the sensor. The SY and unbranded units let you customize tire size for accuracy, and the CatEye Velo Wireless lists 27.5 and 29-inch wheels. Mount the sensor where the listing says, front wheel only for the Padrone, and keep it within its stated range of the display.
