TRAMPA's Generation III PRO BELT DRIVE Motor Mount is a work of art! Made predominantly from T6 Aluminium, every piece has been precision made to give simple assembly & maximum performance.

The Pro Belt Drive Motor Mount will give you the same kind of performance as experienced when riding an Enduro Motor bike, it uses a lower gearing ratio of 4.71:1 giving a higher top speed when compared to the Spur Gear Drive setup - which has a higher gear ration of 5.9:1 (for better acceleration).

The Gen III Pro Belt Drive Motor Mount will only fit to Precision CNC Hangers, using TRAMPA's special Conical Clamping system to securely attach onto the Hanger. The Assembly of any of the Pro Motor Mounts is incredibly sturdy & robust; perfect for the rough terrain they’ll be ripping across.

Accommodating a 66 Tooth Slave pulley, it is possible to adjust your gearing by swapping between 13, 14 or 15 tooth Motor pulleys.  13 tooth motor pulleys are perfect for hill climbing, whereas 15 tooth pulleys will achieve a higher top speed, & 14s are a nice balance between the two.

You can further adjust the performance by changing the Rear Drive wheel size. Changing from 8” to 9” or 10“ Tyres has a massive effect on the performance of the board. Check out the Pro Belt gearing chart to see estimated top speeds of different tyre & pulley combinations.

It is only possible to fit the TRAMPA 5 Spoke Hubs to Pro Drive Slave Pulleys. This means the 5-Spoke Superstar & Megastar wheels fit no problem. However it is only possible to run 8 – 10 inch tyres on the Pro Drives, due to low clearance around the housing tubs.

Enclosed within the Motor Mount tub is the Belt Tension Roller - a Bearing Mounted in Aluminium housing, that guides the belt into the optimum position/tension, to maintain the max amount of grip between the belt & the pulley.

Its possible a belt can snap for a variety of reasons. If you’re the kind of rider that likes to go off into the wilderness, then you should always ride with a couple of spare belts (when one snaps, chances are the other isn’t far off).  TRAMPA's Pro Belt Drive utilises two special cut-outs that ‘ejects’ broken belts from the housing – slimming the chances of snapped belts jamming up the Motor Pulley.

The best way to prevent a belt snap is to check over & replace the Pulleys & belts on a semi-regular basis - BEFORE they have chance to fail on you. Riding, accelerating & braking hard will wear out your belts & pulleys faster. We recommend you service your board every three rides, or after any particularly tough ride. Check the hardware is tight, the belts aren’t worn, & for any damage, particularly to the motor mounts/trucks. Ensure the tub is free from any dust/dirt. Servicing your board is important for keeping it running smoothly, as well as for your safety when riding.

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.

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

This ia 415mm 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.

66 Tooth x 20mm wide PRO BELT DRIVE Slave Pulley with Pressed bearing to fit into the NEW 20mm PRO BELT DRIVE Motor Mounts

As the 20mm wide 66 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 66 Tooth Pulley needs to be correctly positioned on the axle to ensure the belts align perfectly with a  9.5mm spacer.
So if you don't already have one, then you WILL NEED a 12x 16x 9.5mm 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...

M4 x 10mm TORX Countersunk bolt Marine Grade Stainless Steel

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.

Longboard & Skateboard Bearings (8 x 22 x 7mm) Red Black Blue White or GREEN Ceramic sidewalls ABEC 7 608

TRAMPA's Longboard bearings will fit to all classic Longboard & Skateboard Wheels.

TRAMPA's Skate sized 608 Bearing (8 x 22 x 7mm) is internationally known as 608 2RS Longboard Bearing or Skateboard Bearing. It is the High Precision stock choice of bearing supplied with all TRAMPABOARDS that use 8mm Axles.

TRAMPA's 608 Skate Bearing has been polished to a an above genuine ABEC 7 quality rating & offers fantastic performance to the user. This Bearing will spin very fast for prolonged periods & it with regular servicing & a few drops of Speed Cream every now & then will last you a very long time. too. The internal Ball Bearings are mounted in a stainless steel raceway & are coated in very fine grease similar to the properties of Speed Cream.

As with all of TRAMPA's Bearings this Longboard Bearing has been fitted with Friction Free (contact-less) Removable Shields making servicing really easy. 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.
