The ideal and powerful electric folding bike

The BESV PSF1 is made for modern cyclists who crave speed and freedom. The PSF1 retains BESV’s well-known stylish design and combines it with a thoughtful folding feature.

Quick and easy to fold

Six simple steps:
1. Switch the bike to the highest gear
2. Set the pedals vertically and fold in the stand
3. Unclip the rear wheel and fold it inwards
4. Snap off the front fork and fold it down
5. Click the handlebar loose and fold it down
6. Lower the saddle

Size: When folded, the PSF1 is only 84 x 33 x 77 cm: easy to pick up, and compact enough for any trunk.
