BESV managed to combine design with comfort and utility when they designed the easy-mount JS1 cast-aluminum frame.
The company’s first two e-bike offerings were the slick,
fully suspended, compact PS1 with 20-inch wheels and the
stylish, full-size LX1. Both models earned industry design
awards, and each looks more like a concept bike than a production unit. The BESV JS1 shares nearly all of the technical
wizardry of the LX1, but it looks more like a hip, European
city bike with a low-step, cast-aluminum frame. It is designed
for longer commutes, and while it has a good deal of style, it
has a list of details that should give it wider appeal. Features
like the integrated battery; high-output, built-in LED headlight;
and the large data display are shared with the LX1. So is the
powerful hub motor and seamless pedal-assist programming.
We spent some time riding the JS1, and like the LS1, we
were impressed with the performance and the quality of the
pedal-assist programming. There are three levels of pedal
assist, plus a Smart mode, where the bike automatically
adjusts the power level to keep the assist at the optimum
level. The 36-volt, 11.2-amp-hour battery is enough for the
intended use of this model. Where the LX1 has hydraulic disc
brakes and a Shimano XT 10-speed cassette, the JS1 has a
Shimano Alivio nine-speed with cable-operated disc brakes.
For those looking for a sleek, sporty commuter, the JS1 is a
nice choice. ■
