It's a case of "one motor to power them all", say OneMotor, and it will work on anything from recumbents, folding bikes, tandems and three wheelers, not to mention your regular road or mountain bike. The system weighs just 2kg and has up to 40 miles of range, and the power and speed limits are controlled via a phone app.
OneMotor are claiming their mounting system is the most versatile ever created, with the battery mount made by Topeak able to fit to standard water bottle cage braze-ons. The Smart Tyre-Drive can adjust for all weather conditions and mounts to either a front or rear wheels. The pedal sensor simply snaps on in seconds, and as well as detecting the motor activation it also monitors your pedalling cadence constantly.
OneMotor has now officially launched and they're taking pre-orders, with a compact version costing $1,249.00 and the Extended at $1,449.00. Head to onemotor.co for more info.
