This Bikfun city bicycle has a battery to assist you when you need it. It has V brakes and 6 speed gears. It has a 36v 10AH lithium ion removable battery. This means that you can take it off to charge it, although it can be left on for charging if you wish. It will help you to get up to speeds of up to 15mph for 15-25 miles. There are also bright LED headlights and a horn so you can stay safe. The basket of the front and luggage rack on the back also means that there is plenty of space to carry everything that you need.
