BESV is part of the Darfon Innovation Corp. which, is the world leader in producing integrated laptop keyboards. The name BESV oddly enough stands for  Beautiful, Eco-friendly, Smarter, Vision which are the principles that have guided the development of the JS1.(Marketing!)

The BESV JS1 pedal-assisted electric bicycle features a strong, durable frame, for long-lasting performance. JS1 is ideal for short rides to the park, a quick spin around the neighbourhood, or even longer rides in the countryside. Equipped with our advanced proprietary Algorithm power drive system, the JS1 delivers a smooth ride, every ride.

A comfortable and practical city-oriented electric bike with integrated lights, full-length aluminium mudguards,  suspension fork with remote lockout and ergonomic grips.

The TDCM  500 watt gearless hub motor is near-silent but powerful, beautifully designed custom downtube battery pack, integrated LCD display unit.

This bike comes with an excellent warranty (two years on the battery and motor), only available in one size but you get two colour options, key must remain in while riding

The JS1’s dip-frame is easier to mount and dismount than a normal bike, and the design also creates a more balanced ride. The concept subverts conventional triangular frame design to make riding universally easy, no matter the rider’s age, gender or clothing.

This bike comes in one frame size, it’s pretty adaptable to short and mid-sized riders and offers a comfortable and safe upright seating position.
