Maria L. Verified buyer Aug 2025

Battery life is legit—did 42 mi on PAS 2–3. Hydraulic brakes feel solid in rain.

Jordan K. Verified buyer Aug 2025

Folds into my SUV easily. The half-twist throttle is smooth for traffic.

Quinn R. Verified buyer Jul 2025

8-speed pairs well with PAS. Swapped the saddle for longer rides.

Sophie D. Verified buyer Jul 2025

Bright “angel-eyes” headlight makes dawn rides safer. Love the magnesium frame.

Arun P. Verified buyer Jun 2025

I’m ~95 kg—still pulls strong. Kenda tires grip well on packed dirt.

Leah M. Verified buyer Jun 2025

Heavy up stairs (big battery) but worth it for the range.

Diego C. Verified buyer May 2025

Assembly was straightforward. LCD is easy to read in sun.

Nina S. Verified buyer May 2025

Mine had a small cosmetic scuff—support sent touch-up. Rides great.

FAQs

Please read our FAQs page to find out more.

Can I use the throttle the entire ride?

Yes, you can --that is what it is there for! However, using the throttle the entire time you are riding will impact how long the battery will last, getting you 20-40 miles on a full charge. (The specific mileage depends on the model)

How far can I go on the ebike on a full charge?

Up to 60 miles, more or less depending your riding style, level of pedal assist an/or throttle, rider weight, hills, and headwinds/tailwinds.

How long does it take to recharge the battery?

Charging the battery from empty to full typically takes 5-6 hours. In rare cases, it may take longer to allow the battery management system to balance the battery, particularly when the bike is new or after long periods of storage.

What to do if the battery cannot be charged?

Check whether the indicator light of the charger is displayed normally, test whether the output voltage of the charger is greater than 48V, and troubleshoot the charger first.

If there is no problem with the charger, it is likely that the fuse of the battery charging port is damaged. You can try to go to a local repair shop to replace the fuse.

If you still can't solve it after replacement, please provide a video showing that the battery cannot be charged, provide order number, and contact after-sales,
