What a bike!!

Have been looking at E bikes for a while. After some research i discovered BURZERK and emailed Adam for more information. After a few phone calls and finer details i decided to order one of his bikes. Communication and delivery was good and was very easy to assemble. Im very pleased with the bike and the whole experience and would not hesitate to reccomend one of these bikes
