TRAMPA's Generation III SPUR GEAR DRIVE Motor Mount is the ultimate drive system for off road riding! Made predominantly from T6 Aluminium, every piece has been precision made to give simple assembly & maximum performance.

The performance from the SPUR GEAR DRIVE Motor Mount is likened to a Motorcross bike - designed with insane torque for astonishing acceleration, top speeds & jumps. Opposed to the PRO BELT DRIVE Mountainboard, which is designed like a Motor-Enduro bike - for longer, more comfortable rides, and a bit more top-end speed.

The SPUR GEAR 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.

The SPUR GEAR DRIVE uses Helical or Straight cut gears. Helical Gears give a gear ratio of 1:5.8, whereas straight cut gives 1:5.9 – meaning straight-cut gears have more power when accelerating - however, Straight-cut gears are louder than the Helical when riding (although we’ve found some mad people who like the noise!).

You can further fine-tune 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 Spur Gear 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, 9 or 10 inch tyres on the Pro Drives, due to low clearance around the housing tubs.

Spur Gear Slave Pulleys are made using premium POM plastic, giving them the best strength : weight ratio possible.

TRAMPA's EXTERNAL SPUR GEAR DRIVE is housed within a super strong, rubber-sealed Tub, CNC’d from a solid block of heat-treated T6 Aluminium. Ensuring all the moving parts are safe from the elements, as well as knocks and bumps that come along naturally when riding.

We recommend you service your board every three rides, or after any particularly tough ride. Check the hardware is tight, the gears are greased, & 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.

TRAMPA's MkIII SPUR GEAR DRIVE (SGD) Motor Mount is a Super Powerful drive system that's designed to give maximum performance. It is the perfect option for 'Serious Off-Road Riding!'

The performance from the SPUR GEAR DRIVE Motor Mount is likened to that of a Motor-Cross bike - The solid gears inter-lock & as the motor turns supplying instant propulsion! There can be no 'slip' no matter how hard you push. 

The SGD has insane torque & gives astonishing acceleration. but it is still able to easily achieve, through a selection of different gearing options for different types of riders a 30mph+ top speed... Capable to handle aggressive riding, this board can be being ridden in the worst of conditions & also very good at hitting fair sized jumps like those found on your local BMX park. 

Comparably, TRAMPA's PRO BELT DRIVE (PBD) Mountainboard, which many customers wonder if this is the right board for them compared to the SGD, because of its sturdy Black anodised Aluminium protective Tub makes the Pro Belt Drive setup a sealed off system and just like the SGD preventing the the likes of crap from getting in, the PBD can still be ridden in bad conditions but is designed with gearing that is more like that of a Motor-Enduro bike which is less aggressive acceleration but therefore a higher top speed & should be selected for longer flatter rides as its somehow more comfortable for these kinds of rides & gives you a bit more top-end speed at the same time....

TRAMPA's 'SPUR GEAR DRIVE Motor Mount' will only fit to Precision CNC Hangers. Constructed using TRAMPA's special Conical Clamping system which securely tightens itself onto the Hanger, the Assembly of any of the TRAMPA Motor Mounts is incredibly sturdy & terribly robust 100% perfect for the rough terrain they’ll be ripping across.

The SPUR GEAR DRIVE Pulleys are produced in 2 ways. Originally using light weight POM material (Which is great for light weight riders) & now being also offered in Heat treated Steel alternatives (Which is great for the larger riders). POM is like a re-enforced plastic material & much less Heavy than a Steel option. The POM Pullies are offered in a 58 Tooth Helical cut (supplying a gear ratio of 1:5.8) &/or a 59 Tooth Straight cut gear (supplying a Gear ratio of gives 1:5.9) so the Straight cut pulley has 1 tooth more which means it will accelerate slightly faster than the 58 Helical (but barely anything in it really). 

Its claimed the Straight-cut POM gears run slightly louder than the Helical POM Gears, although the slight increased noise can be quite nice to hear, it gives a sense of speed & can be quite useful to alerting ramblers or pedestrians you are approaching or likely to approach around a blind corner that you might be traveling too fast into and therefore the slight noise alerts our fellow citizens of our approach which takes the fright of a surprise out of your potentially fast approaching presence... :-)

 Both POM Pullies options are wonderful for the lighter weight riders, say up to 80kg in weight, but sometimes not robust enough for the larger sized riders out there, 80kg+.... If your an aggressive rider but light weight then you should consider taking the steel Pullies as they are stronger for sure...

& so larger sized 'Fully grown BigBoys' out there that want the same performance as the light weigh riders they see in the videos they need the strongest equipment & with more gearing ratio to allow their extra weight/mass to have almost the same incredible performance as the lighter weighted riders, so we have made some Heat treated STEEL Slave Pullies. That's a ratio of 1-7 and will give incredible torque! So for riders that are big and need some gearing to shift them forwards fast, the 9/63 is the one for them. If your a light

CNC'd from a Solid Block of Super Strong Aluminium the SGD Tub is T6 Heated before being presented to you in a Glossy BLACK Anodised finish, with a TRAMPA logo running down its facing edge to give incredibly smart & co-ordinating good looks as well as maximum performance 100% of the time!

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.

The head of this Bolt is COUNTERSUNK, meaning that when screwed into position it sits flush & neat with the surface its screwed into. Preventing bolts from standing proud eliminates the chance of anything getting "snagged or hung-up" should it get caught on something..
