TRAMPA's 44 Tooth Slave Pulley has been designed to be used specifically when connecting electric motors through the URBAN Motor Mounts when using the new & oversized, super grippy GUMMIES longboard style tyres. The Gummies Tyres are due out very soon & available on advanced sale now! Frank was un-able to design 1 pulley to fit both styles of TRAMPA hub, so this one will only work with HYPA hubs specifically.
The 44 Tooth 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 Premium 15mm wide German made 'Strongbelt' & when the Strongbelts are wrapped around the pulleys, the belt fits so efficiently it has what we call HIGH TORQUE DRIVE (HTD). HTD insures all of the motors Torque is pushed through the pulleys into the wheels & when coupled with the amazing VESC 6 & 12s Battery power provides instant smooth unreal Power on tap to the rider!
This smaller sized 44 Tooth pulley is actually higher in gearing than the 66 tooth & therefore when fitted it increases the final drive (top Speed) compensating for the smaller sized final drive the wheel was originally intended to fit to... Gummies tyres only measure 125mm which are obviously smaller than 6.5, 7 & 8 inch wheel options we also offer so the Gummies Tyres love the extra gearing the 44 Tooth Brings :-)
TRAMPA's 44 Tooth Slave Pulley for HYPA hubs works in conjunction with all & any of the 13, 14 or 15 tooth Motor Pulley in the range. Changing your Motor Pulley will drastically alter the performance & characteristics of your ride... 13 Tooth motor Pulley is best for Hill Climbing whilst 15 Tooth Motor Pulley is best for high speed, 14 tooth motor Pulley will give you good all round performance...
To connect the 44 Tooth Pulley to the HYPA hubs you will need 6x M4x40mm Socket capped Bolts which screw throurgh the HYPA wheel assembly directly into the Pulley very neatly!
