FAQs

Please read our FAQs page to find out more.

What are hub motors?

Hub motors are located in the wheel hub. They present low maintenance requirements and provide consistent power delivery on flat terrain.

Is the battery removable?

Yes. The battery is removable and can be charged on or off the bike. You can lock it on your bike for high security.

What kind of assembly is required?

Your e-bike will arrive partially assembled (about 85%) and packaged in a standard bike box. The parts that need to be mounted include the front wheel, front mudguard, headlight, saddle, pedals, and handlebars. You can check the manual for a step-by-step guide.

Can I ride this bike on a rainy day?

All of the electric components, including the battery pack, are designed to be water-resistant. However, we strongly recommend keeping it indoors on rainy days or in bad weather.

 I’m 5'8". Can I use this bike?

 Yes. The recommended rider height for J1 is 160-200cm (around 5' 3"-6' 7"), and for J1 ST is 155-195cm (around 5' 1"-6' 5").
