BAFANG 1100W Power

The C1 features a 1100W outer rotor BLDC motor from the BAFANG sub-brand. The motor is equipped with a 5-level pedal assist system (PAS). At level 1 PAS, the controller can deliver a torque of up to 90 Nm, while at level 5 PAS, the speed can reach 28MPH or higher. The motor utilizes a sinusoidal wave structure and can rotate at a speed of 3805 revolutions per minute within one minute. The BLDC motor boasts low interference, low noise, smooth operation, high speed, high temperature resistance, and a longer lifespan (over 100,000 hours), ensuring stability and reliability in various complex environments and prolonged riding sessions.

Equipped with Samsung 48V 11Ah battery

The C1 electric bike utilizes Samsung 21700 lithium-ion batteries, which offer significant advantages in battery performance compared to traditional 18650 cells. 21700 batteries generally have higher capacity, allowing them to store more energy. Additionally, they boast a 6% higher energy density than 18650 batteries, meaning they can provide longer range or higher power output within the same volume. Furthermore, the C1 electric bike features a concealed battery structure, positioned on the upper tube for easy removal within 3 seconds, and it achieves an IPX6 waterproof rating.

C1 Xpress Step-Through Design

The step-through design of C1 allows more consumers to experience the joy of cycling and provides excellent accessibility for those with mobility challenges. The frame of the C1 is made from integrated 6061 aluminum alloy, ensuring a robust and supportive riding experience.

So good, bought a 2nd one...

Bought first 'step through' model, so she could accompany & keep up with me on my 15-20 mile 'road bike' rides. Arrived sooner than promised. Incredibly well packaged. No damage whatsoever. 85% assembled and took ~60 minutes to unpack & assemble. Tools included, how great is that! I LOVED it (test ride) and my wife liked it too. Our rides are much more fun and she uses the variable power/pedal modes to get some great exercise and can use full power when she needs to. After a dozen plus rides, no issues and battery life is excellent. (just haven't done that long a ride...yet).
Fast forward 1 week...after I took a leisurely ride (1.5 miles) to grocery store and back one evening, I thought about how nice it would be for both of us to take some leisurely evening rides together.
Sooo...I bought a second Aipase-bike. EXACT same experience; delivered early, well packed, easy to assemble (especially the 2nd time around), everything works well (mechanicals, battery, etc.). Now my wife AND I enjoy evening rides with a little exercise and sightseeing (and I still take my road bike out for the more aggressive exercise). 5 Stars for both bikes (and a very happy couple).

This thing is amazing

I have been eyeing this bike for months and finally saved up enough to get it. Definitely take the time to go over the manual and practice riding before going on the rode. The battery life is really good I went 3 days riding it with out charge. Charging the battery does take 3-4 hours. I use the the full throttle and the pedal assist for hills it's a relaxing way around with little strain unlike a pedal only bike. Don't let the price be deceiving it is definitely worth it

High-end features in a modestly priced bike

Sturdy, reliable e-bike, comfortable to ride without pedal assist, and a real treat on those uphill stretches. I don't need a lot of power but this has enough for people who might use it to commute or who want to travel good distances. I like everything about it.

Well built and really fun. Highly recommend

Assembly wasn't easy but the bike is really nice and so much less than many others. I have had it for about 1 months now and my wife loves it. It almost looks like a regular bike. Sleek with smooth power delivery. Will definitely be buying another in a different color when their prices match the grey one.
