460 long x 20mm wide High Torque Drive (HTD) 5M (5mm Tooth Space) MIGHTY for Open Belt Drive Motor Mounts

This ia 460mm long x 20mm 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 Mountainboard.

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 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. 

Belt Tension Roller Housing for 20mm Belts

Ensuring that belts are correctly tensioned and positioned is an important part of setting up and maintaining your board. A poorly tensioned belt is far more likely to snap or slip, both of which are highly undesirable when your belts are also your brakes!

Made from T6 Heat-treated Aluminium, these Belt Tension Rollers are to designed to house a premium TRAMPA 608 BEARING, ensuring a smooth and consistent roll while tensioning the belts. Used with 20mm belts on OPEN BELT DRIVE Motor Mounts.

Sprung Steel C-CLIP used inside the Belt tension housings to secure 608 bearing

Ensuring that belts are correctly tensioned and positioned is an important part of setting up and maintaining your board. A poorly tensioned belt is far more likely to snap or slip, both of which are highly undesirable when your belts are also your brakes!

These C-Clips ensure the 608 bearing is secure within the Tension Rollers

Step SPACER used for positioning the 15mm Tension Roller on OBD Drive

Ensuring that belts are correctly tensioned and positioned is an important part of setting up and maintaining your board. A poorly tensioned belt is far more likely to snap or slip, both of which are highly undesirable when your belts are also your brakes!

These Spacer-Axles have two functions, correctly positioning the 20mm Tension Roller, as well as providing the housed 608 bearing a snug-fitting axle to spin freely on.

76 Tooth x 20mm wide OBD Slave Pulley with Pressed bearing - fits 20mm OPEN BELT DRIVE Motor Mounts

As the 20mm wide 76 Tooth OBD Pulley is supported / mounted on the axle with a press fitted bearing, when you then include the 2x bearings in the wheel, there are therefore 3 points of mounting contact on the axle in the assembly of the Motor drive when fixing to the wheel giving a very nice well balanced secure fit ensuring maximum performance at all times.
The power of the TRAMPA Motors is huge & to have the power spread across the axle is important to the delivery of smooth performance...
The 76 Tooth Pulley needs to be correctly positioned on the axle to ensure the belts align perfectly with a  9.2mm spacer.
So if you don't already have one, then you WILL NEED a 12x 16x 9.2mm Spacer to position the pulley & wheel in the perfect location on the axle to acquire maximum Torque 

You may also need some M4 x 20mm Hex spacers & M4 x 10mm Dome Head TORX Bolts to fit this pulley to your wheel.... 
As this Pulley has 5 spokes, it is specifically designed to only fit to any the 5 spoke hubs that TRAMPA produces. So TRAMPA's SUPERSTAR 8 or 9 inch Megastar & PHATLADS hubs...

Custom 20mm wide Steel Motor Pulley 13, 14 or 15 tooth

TRAMPA's 20mm wide 13-15 Tooth Motor Pulleys connect directly to the Motor Axle & are secured into position using a Magnetic Fixing Key & 4mm Locking Grub Screw.

This custom made Motor Pulley Wheel  fits 20mm wide STRONGBELTS, which should never stretch or break whilst at the same time providing a very smooth power delivery to the user - even from a standing start.

Changing your Motor Pulley &/or Drive pulley wheels will drastically change the performance of your ride... :-)

It connects into the Motor Pulley when mounted onto the motor Axle Shaft & is used to center the pulley on the Axle & to assist in delivering all the power from the motor without slip! This KEYWAY will fit to all TRAMPA motors amongst others.

TRAMPA's Axle length measures 38.5mm (from motor housing to end of shaft) & has a Diameter of 8mm. The centre of the key (3 x 3 x 8mm) sits 16.70mm away from the Motor front. Front side of Motor to Center of Key! Deduct 4mm & you have the length from front side of motor to the start of key....

OBD Motor Mount Connector Panel for 76 tooth Pulleys - REGULAR or GOOFY

OBD Motor Mount Connector Panels are an all-in-one Mounting Panel & Truck connector, CNC’d from premium heat-treated T6 aluminium. Motor Mount Connector Panels are available in two models (66T or 76T), each designed with different gear ratios (therefore different performances) in mind.  

OBD 76T uses the 76 tooth Slave Pulley with a gear ratio of 5.43:1 - giving an amazing level of torque (similar to the Spur Gear Drive), and performance favouring insane acceleration over overall top speed. Due to clearance, OBD 76T Systems can only use 9 inch Wheels.

M4 x 10mm TORX Dome/Button Headed Head Bolt 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. 

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.

To Service your Bearings use a sharp knife or 'Pick' to carefully take out the Removable Sleeves from the bearing & clean/soak the bearings in a pot of Petrol or Thinners. Once clean, dry thoroughly & add a few drops of Speed Cream. A few drops is more than enough so don't go pouring loads in, the oil just needs spreading over all of the surfaces so pop them on the axle & give them a spin to spread the cream evenly & only add 1 more drop of Speed cream if necessary. Remember to wipe up any excess cream spinning out of your bearings onto your wheels as this will attract dust & dirt looking messy in turn.
