This is an Engwe electric mountain bike which comes in a green colour. It folds up too which means that the light aluminium frame is a very useful feature as it can easily be lifted up. It has 20 inch wheels which means that it can cope with road and trails. It has front and rear disc brakes for safety and a Shimano 7 speed transmission system. It has a soft leather sea and fat tyres which means that it is very comfortable to ride. The 48v battery can help you to travel faster or give you a bit of a rest and can manage 25 miles before the need to recharge.
