M4 x 4mm Grub Screw M4 x 4mm Motor Pulley Grub Screw - Connects the Motor Pulley onto the Motor Axle Shaft

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.

M4 x 10mm TORX Dome/Button Headed Head Bolt DIN6912 Marine Grade Stainless Steel TORX

TORX Screws are less likely to strip out when compared to a hex screw, because of the way the load is distributed and applied between the tool and the hardware. Because of this load distribution, the height of the head of the bolt can be reduced - making them nice & flush.

460 x 20mm HTD 5M HP - OBD 76 Tooth Motor Mounts

This ia 475mm long x 15mm wide High Torque Drive (HTD) Re-enforced Rubber Belt, which has 5mm Tooth Spacing (5M). This Belt is High Power rated (HP) & arguably over engineered for our application as the belt is made in Germany by the world famous company called STRONGBELT, who usually supply into heavy industry public sector applications which demand much more stringent requirements of any electric skateboard! This belt is used to transfer the power from the Motor & Motor Pulley into power at the rear wheels of a TRAMPA Electric URBAN Carveboard

TRAMPA opted to set a new standard in E-Skating, becoming the first in the world to fit to all of its E-Boards, a 15mm wide TRANSMISSON BELT. Our standard 15mm belt is almost double the width of nearly all other E-Sk8's out there, they tend to use a flimsy off the shelf 9mm transmission belt which are prone to stretch, slip & ultimately snap. Using a re-enforced 15mm wide High Power Belt reduces stretch, eliminates slip & as a consequence provides a constantly smooth whilst incredibly intuitive power delivery direct to the rear Drive Wheels of your board. When accelerating or engine breaking (KERS), even from a standing start the STRONGBELT power is smooth & does not slip, or strain the motor, it does a damn gooood job!.....

STRONGBELT, as their name suggests, is a Heavy Industry German Brand that usually supplies the likes of Train manufacturers and other Public sector applications where serious levels of quality with no excuses on failure are expected from the product, as failure for such an item is serious & may result in death! STRONGBELT weave KEVLAR into their Pulley Belts, Kevlar is one of the strongest fibers known to man, its often added into materials to gain extra strength.... STRONGBELT have the best reputation in the Power Transmission Industry for NO stretching or snapping & we have high expectations from this quality item. 

These extra quality details in the production of our electronic motor drives, provides the maximum responsiveness achievable whilst maintaining a super smooth power delivery to the rider at all times.
