Product Description


High Capacity Battery

The battery for this electric bike kit not only looks great but also serves a functional purpose. Providing up to 80 km of range, this kit is one of the best on the market. In addition to being removable and lockable, this 10Ah Lithium battery comes with a very handy USB charging port to top up your phone and power your USB devices.

Free Upgrades

Electric bike kits used to be frustrating to install, in an effort to remove this barrier we include free upgraded wiring and waterproof plugs as well as our new innovation RPAS. This has made the experience of installing your electric bike kit a lot faster and more enjoyable. Another benefit is quick wheel removal should you need to access it for replacing the tube or fixing a puncture.

Improved Hub Motor

Dillenger has engineered this 36V electric bike motor to output greater torque, helping you tackle hills with ease while still providing you with a zippy cruising speed of 25 km/h. Integrated into the hub with a polished finish, this kit looks great as well.

Best Seller

We have worked very hard on creating the best electric bike kit for the lowest price on the market. Hitting the perfect medium between performance, reliability and range, it is no wonder this has become our fastest selling and most favoured kit.

Will the NT battery fit my bike?

Sizing up your NT batter to your bike


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.

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.

Excellent Kit with great service and speedy delivery!
I received the kit faster then expected.
Installation was fairly easy. I am picky so I took my time.
Installed on a Giant Hybrid Cypress DX Xlarge
Did not install the throttle - did not want one. Plus I have rotating shifters on my handle bars.
Swapped my brake levers with the ones from the kit (I have extra long levers)
Had a few questions during the installation, and got quick fast answers every time!
Today I got to use the bike.
It worked great did 20 miles, it was a great ride easy against the head wind and up and over two bridges. Battery level still shows full - I mostly rode around 14.5 Mph using PAS level 3 - just my speed! - total average was 13.4 mph
I really like this kit and highly recommend it to anybody looking for a simple long distance E-bike upgrade kit (Posted on 27/05/2015)
Overall an excellent product.Review by David

Installation is very straight forward and the components are well made. One slight reservation is the fixing of the pedal assist sensor, personally I have used cable ties instead of the adhesive pad supplied. Delivery and packaging are excellent but it is sometimes difficult to get a response to any technical queries.

Overall though this is an excellent product at a very good price. (Posted on 20/05/2015)

As a aged pensioner, Conversion Kits from Dillenger are affordable compared to competitors, As I have arthritis in my knees and hips and I ride 1,500 km per year around a caravan park doing chores on my 20” folding bike, now I have a Conversion Kit, I have a bike for both worlds, Exercise and Pleasure. The Conversion Kit was so easy to fit; all I needed was to purchase a tool for the crank removal. Well-done DILLENGER for a great Conversion Kit.

Hey I love my new electric bike, since installing the Dillenger street legal kit on my bike I just want to get out and go for a ride every chance I get. I would have to say it’s my favorite new toy! The Dillenger 250W electric kit has added a whole new dimension of pleasure to my ride. It has plenty of power for going against the wind and the pedal assist works great going up hills, it’s very quiet, which also adds to the enjoyment of the ride. So much FUN to ride, I Love it!

My classic Jesse James chopper bike has a new life. It took less than one hour to install my new 250W street legal Dillenger kit, now I’m cruising along at 30km with a huge smile on my face, thanks soooooo much Sam. Peddling this single speed bike up hills and into a headwind is so easy now and so much more enjoyable. I have put away the car and ride to work now 4 days a week, I’ve lost 15kg and feel much healthier for it. The best thing I like about this conversion kit is the way it looks almost invisible, its lightweight, easy to charge and comes with a 2-year warranty. WOW. Everyone I know has had a ride and they all want one. Great value for money highly recommended. (Posted on 19/06/2014)
