Spur Gear Drives are compatible with Straight-cut or Helical Gears.
Made from premium POM plastic
, the 58-tooth Helical Slave Pulley pairs with the 10-tooth Helical Motor Pulley, giving a gear ratio of 1:5.8. Compared to the 59-tooth Straight-cut Slave Pulley’s ratio of 1:5.9, Helical gears will ultimately have a higher top speed.  

Helical Gears provide more surface contact between the teeth, resulting in a smoother & quieter ride.

Straight-cut Gears are the cheaper option – still providing amazing torque & performance, while running a bit louder than helical.   

Connects to Hub Adaptor using 5x m5 x 12mm Torx head screws.

M5 x 5mm Black Steel Grub Screw Marine Grade Stainless Steel - Connects into Motor Mount to give Axle position on Mountainboards

Made from A4 Marine Grade Stainless Steel, all of the nuts, bolts & screws used in a TRAMPA board have proven to be up to the challenge of holding everything together. Using Marine Grade Stainless Steel also means these Bolts will never rust on you! They can cope with the harshest of weather conditions & will laugh in the face of sandy/salty beaches or muddy freeride tracks - which can turn other manufacturers’ nuts & bolts into corroded rusting wrecks!

Wherever possible, we dip all our bolts into BLUE THREAD LOCKING PASTE, to ensure an extra strong & secure fix between the nuts & bolts.

Spur Gear Drive 10 Tooth HELICAL or STRAIGHT-Cut Motor Pulley

SPUR GEAR DRIVE Motor Mounts can run using Helical or Straight-cut pulleys.

Helical Motor Pulleys give a gear ratio of 1:5.8 when paired with the 58 tooth Helical Slave Pulley. The Helical shape allows for more surface contact between the Slave & Motor Pulley Teeth, creating a quiet & efficient drive. 

Straight-cut Motor pulleys pair with a 59 tooth Slave Pulley, giving a ratio of 1:5.9 – meaning there will be a tad more power when accelerating in comparison to the Helicals. However, due to less surface-contact between the gears, Straight-cuts are much louder when riding along (although we’ve found some mad people who like/prefer the noise!).

Made using Hardened Steel.
