TRAMPA's 66 Tooth URBAN mount Slave Pulley fits to any of the HYPA, SUPERSTAR or PRIMO wheels in the TRAMPA product Range & are used when connecting electric motors to the URBAN Motor Mounts.
The 66 Tooth URBAN Slave Pulley has been precision milled from super-light-weight & mega strong Heat Treated T6 Aluminum. The pulleys teeth stand 5mm tall, this is the same size teeth as that found on TRAMPA's 15mm wide 'Strongbelt' & when TRAMPA's Premium Strongbelts are wrapped around the pulleys, using the belt tension facility to screw down & increase the tension on the belt the connection between the teeth & the belt becomes so efficient it has what we call HIGH TORQUE DRIVE (HTD). HTD ensures all of the motors Torque is forced through the pulleys to the wheels & when coupled with the amazing VESC 6 & 12s Battery power provides instant smooth unreal Power on tap to the rider!
With the use of some very special Threaded Hex Spacers & Socket capped Bolts the 66 Tooth URBAN Mount Slave Wheel connects directly into any of the GUMMIES, 6.5, 7 or 8 Inch SUPERSTAR or HYPA Wheels as well as into the PRIMO 3 spoke 9 Inch wheels to give a massive final drive... - 1 pulley, 3 uses, Amazing! :-)
TRAMPA's 66 tooth URBAN Mount Slave Wheel works in conjunction with all & any of the 13, 14 or 15 tooth Motor Pulley in the range.
