    Dahons and other small folding bikes with narrow forks that require the specialized Brompton kit featuring a narrow motor to fit in the forks. The Swytch Brompton kit is the only conversion kit worldwide that is compatible with Bromptons and other bikes with narrow forks, as no other company offers the narrow motor that fits in without permanent modification of the bike. This specially designed compact motor increases the price of the kit.
