Premium Off-Road Conversion Kit - back in stock!

From the success of the Vermillion high performance off-road electric bike, Dillenger brings you our newest high-powered conversion kit based on the same geared BLDC power plant. This is powered by a monster battery pack boasting a massive 624Wh of capacity. This premium off-road kit is an evolution away from the direct drive 1,000W and 1,500W off-road kits and instead adopts the super high torque newly developed 500W geared BLDC rear wheel motor. With a 13Ah 48V battery pack using a high discharge, high capacity Li-ion cells you won’t worry about chewing through the capacity at such a prodigious rate.

Product Description


No more range anxiety

624Wh of capacity is a huge amount of energy, but at a high discharge potential it’s important to know that your fun will last all day. We had a great deal of feedback from the 1,500W Hardcase we produced in 2016 that showed us customers loved the super long range. The reliability and longevity also increase over the lifetime of the unit where the capacity is surplice to the customer’s needs. So whilst it is a high-end, premium product in terms of the cost of a large battery unit, the benefits present great value and riding experience.

Integrated controller

One of the limitations of previous high powered kits is the use of the detached controller box which was usually mounted under the down tube. One of the big improvements in using this battery case system from Reention is that it allows us to integrate the 22A proprietary controller into the base of the battery cradle. So what you can see in the first image of the product actually shows the controller as well, which is neatly integrated into the battery cradle system. This results in a super clean overall look and is a lot easier to fit, requiring no additional fasteners.

Plug and play

As with all our plug and play conversion kits, apart from a few basic bicycle tools this kit includes everything you need to get up and going. If you require our hub motor conversion toolkit, please check it out here. Apart from these tools, we include everything you need to get going including the motor wheel, battery, cradle/controller, LCD, throttle, pedal assist sensor, e-brake sensor, all the wiring and AU/US/EU approved charger. If your current bicycle uses a cassette style gear set, we would encourage customers to purchase a freewheel from Dillenger or your local bike shop.

Geared hub

We've gradually departed from the large 1,000W direct drive hubs that have served the company so well for so many years. Whilst they hold a dear place in our heart we always got a nice little buzz when trialing the 500W geared options that were available on the market at the time. Unfortunately the BPM hubs that were available at the time had a lot of issues which is why we held on to the 1,000W direct drives for so long. The new 500W Premium kit motor hub is an evolution from our 250W geared hub motor which has had bullet proof reliability over the years. So after a lot of testing and a lot of fun, we've crossed over and haven't looked back! Yes there is a slight sacrifice on top speed but the additonal acceleration and general riding performance is absolutely worth it.


Will this kit fit my bike?

There are thousands upon thousands of different bikes out there, so there is no list to guarantee that it will, however almost all bikes, whether they are mountain bikes, road bikes, cruisers, choppers, BMX or whatever else, have a very standard axle slot width (approx. 10mm), standard front and rear fork dropout widths (approx. 100mm and 135mm respectively) which our kits are universally compatible with. The front-on profile of the motor wheel is also very similar to that of a normal wheel, so clearance on the fork section is also not a drama. If you dropout dimensions are within 5mm of this then that is generally acceptable. To use the pedal assist sensor your bike must have the standard internal bottom bracket bearings and about 4mm clearance on the crank axle on the non-drive side of the bike. If this isn't practical, you can easily use the kit without the pedal assist sensor, or change your bottom bracket.

What Size Conversion Kit Do I Need?

The information you need to know will be written on the tyre of the bike you’re converting. It’s not the diameter of the rim alone, it’s a complicated measurement that is annoying to work out from measurements of the wheel, rim and tyre. The easiest, most straightforward way to know what size you need is to look at the info on the tyre. It should read 20, 24, 26, 28 or 700C somewhere on the sidewall.

What’s The Difference Between 700C, 28″ And 29er?

It’s a complicated measurement and there is often confusion around this question. If you own a 29er, 28″ or 700C wheel bike, you need to order a 700C kit which will be the correct kit for your bike. The 29ers can have wider rims and hubs, so check the dropout clearance prior to ordering. We have not yet had a 700C, 28″ or 29er that has been incompatible. So long as you select the 700C listing and use the tyre that was on your wheel, your 29er will make a great electric bike. The rims in the kit are 25mm wide (outer width) and can take from a 38C tyre.
