okay this was a gift but I know the coolmob got an order of these bikes sent to them and they were very happy. You can put along about 25kph range about 30ks without battery recharge. very eco friendly

Approximate cost: $600-800

I will keep up with their designs there are other things I like but cant afford. my workmates were impressed with the design of the ring. The service was really fast

Approximate cost: $19
