FAQ

Any questions on our bikes? We're here to help!

The i:SY has a single-size frame. The perfectly conceived frame geometry makes it possible. The frame is adjustable in length when people between 150 and 190 cm tall sit on it. Thanks to the flat seat angle and the comparatively “long” top tube this is possible. For people up to 210 cm our XXL models are ideal
All bags and baskets that are delivered incl. a MonkeyLoad-T plate are also fitted with a lock. For our waterproof trunk bags that are fitted with the MonkeyLoad-S system we offer a separate anti-theft. MonkeyLoad-S lock, Art.No. 5020319. 
It is possible in most cases. Our i:SY Front carrier with KLICKfix is compatible with all bags and baskets that have a KLICKfix plate, a BASIL KF or a MonkeyLoad adapter plate. For baskets or crates for the rear carrier we offer the MonkeyLoad-T plate. They can thus be fitted onto the i:SY rear carrier ML ready.
Bosch batteries are of very high quality. That's something you'll notice right from the outset. Low weight, high-quality cells, no self-discharge, fast charging times and a long service life. Assuming normal usage, a rechargeable battery is expected to perform well for a period of five years. After that, it is still a good secondary battery.
