Used The MiRiDER One is a superb commuter bike. Equipped with an all new 250 watt rear-hub motor to assist when pedalling up to speeds of 15.5 mph. It has also been upgraded to perform more efficiently while also providing 25% more torque than the previous model. This ultimately culminates in a zippier bike with an extended range.Love this bike, genuinely superb and especially good if your commute involves a train. It folds down perfectly and comes with a strap to assist the magnet in keeping the bike folded. I would have kept it but I now work from home and dont commute as regularly any more.
