    From our customers


    100% impressed over and over again by Jeff & Co at Revival. They’re patient and kind no matter the enquiry (currently resto-modding an R100/7 and have LOTS of questions about the Motogadget rewire) and go out of their way to offer creative solutions and out of the box thinking. I will forever return and recommend Revival.

    I cannot recommend Revival Cycles enough. Not only do they have a great assortment of gear and accessories but they provide superb customer service. I was having some difficulty making it work... Jeff pointed out what I was missing and also provided schematics to make it work. Thank you guys very kindly, your crew rocks.
