Bicycle Electric Lifting System
Motorised lifting column with a quick-release clamp that sets a bicycle at the ideal working height in seconds — controlled from the handpiece or the foot pedal.
BMX freewheel series in 13T to 18T — three families covering 3-pawl standard, CP-finish ZC and fast-engagement 6/9-pawl types with 72 or 108 clicks, in CrMo steel for 1/8 and 3/32 inch chains.

The DF BMX Series covers freewheels from 13T to 18T in three families: the classic 3-pawl DF-13 to DF-18, the CP-finish DF-ZC16 to ZC18, and the fast-engagement DF-P16 to P18 running 6 pawls / 72 clicks or 9 pawls / 108 clicks. All are CrMo steel for 1/2 x 1/8 and 1/2 x 3/32 chains.
The DF-13 to DF-18 three-pawl freewheels take both 1/8 and 3/32 chains, with the thread changing by size: 13T / 14T / 15T use M30 x 1.0, while 16T / 17T / 18T use the larger 1.375 x 24 TPI — check what your hub takes before ordering.
The DF-ZC16 to ZC18 share the same layout in a black, brown or CP finish, and the DF-P16 to P18 are the fast-engagement option: 6 pawls with 72 clicks or 9 pawls with 108 clicks pick up the drive almost instantly for racing and freestyle.
CrMo steel construction across the range stands up to chainring slap, skid stops and landings; finishes run from black & nickel to brown and polished CP.
