Product Description



The low cost option that does not compromise on quality. Dillenger wanted to make an electric bike kit that delivers on great range and reliability for a lower price. This is a great entry level kit for people looking to convert their bike into a lithium ion powered electric bike.

Sleek Bottle Battery

The li-ion battery included with this electric bike kit fits perfectly in the bottle holder on the frame of your bike. Just fit the custom battery mounts where the bolts are and slip in the battery. Convenient to remove, lock and charge.

Improved Hub Motor

This 36V electric bike motor outputs more torque thanks to clever gearing, helping you tackle hills with ease while still providing you with a zippy cruising speed of 25 km/h. Super easy to install onto the front wheel, you'll be up and running in no time.

Build Standards

All of Dillenger's electric bike kits are built and tested to the highest standards to ensure they are reliable and safe. This is why we can offer an industry leading warranty, giving you peace of mind that if something does go wrong - we will fix 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.

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.

Pleasantly surprisedReview by Jane

Never have I ridden an electric bike and I didn't know to to expect. Well I was pleasantly surprised. It took only a couple of days to arrive and a few hours to install. I've always had a push bike as I don't drive, but this is something else. Zipping along the roads to go to work or the shops is a blast. Even my friends who had a test ride were thrilled with the response of the hub motor. Charging the battery is easy. And changing between modes is a breeze.

The only con I have is the handlebar grips. They are very hard on the wrist when riding for more than 15-20 mins.

Highly recommended! (Posted on 5/12/2015)
Does what it says on the boxReview by Chris

I've had my kit on for about a month now and have to say I love it. I converted my flatbar road bike purely for commuting and I've cut about 50 minutes a day off the commute. The main objective of converting was to be able to ride to work without getting sweaty which means I don't need to change either end and with the conversion I can do that.

The install was very easy (other than trying to get the rusty screws out of the bottle cage!). One thing to be aware of, the roadbike forks are relatively narrow so I had to get a couple of bushes machined to slightly open up the forks but once I did that it worked well.

I get 2 trips to work and back on a charge which is about 24kms in total with very little pedaling. I've done 5 trips (30kms) without a charge so the battery life is as specified.

Overall, great value, does what it says on the box and couldn't be happier. (Posted on 4/12/2015)
It arrived within a few days and installation followedReview by Jack Adriaans

After having a ride on a purpose built European e bike I decided to convert a bike given to me by my children 4 years ago and on which I only clocked up 32 kilometers in that time, due to the hilly terrain in our area. An internet search kept leading me to Dillenger 250 watt Lithium battery conversion kit as being value for money and legally usable on Victorian roads and after a few phone calls and emails with Dillenger to clarify if the dual suspension frame which did not allow for the usual battery mounting site would be suitable, I obtained a seat post rack and ordered the kit.

It arrived within a few days and installation followed, even with limited bike mechanics in my background, the instructions included with the kit allowed completion within 3 hours. I ride daily, the hills are not as daunting, even with all the uphill gradients I can achieve 30 plus kilometers without complete discharge at an average speed of 21 km/h. I enjoy the pedal assist sensor automation but am still able to manually over ride with the throttle and the fact that when I apply the brakes the power is cut off to the motor.

The conversion has not added significant weight to my bike so it can go with us on our winter caravan trips around this astounding country. I now have a bike I use and enjoy, finding it compares very well with the European bike I first tried in features and performance for much less expense. I readily recommend the kit for any under used bike owner, you will get out and about more.

We couldn't be happier with the way the kit worksReview by David and Jenny Tuck

Just a short note to thank you guys for a great value top quality 250w conversion kit.
The kit was easy to install with no dramas at all. Due to a medical condition, my wife had been unable to come with me on rides. We are lucky enough to have kilometers of local bike paths near-by. Now after having the kit for a few months, she is getting fitter and building strength in her legs. She is more than able to keep up with me or, even Crooze ahead of me, pretty well when ever she wants.

Kind of frustrating for me. Now I want one:-)

As well bike the paths, we have been using the bikes to do light shopping and stuff.
The sort of things that before, we would have just jumped in the car to do. All in all, we couldn't be happier with the way the kit works, the quality, and the ease of installation
We wouldn't hesitate to recommend it to anyone who is considering buying an E-bike.

Thanks again,

David and Jenny Tuck

Electric Bikes for us over 60'sReview by Bob Bennett

Overall Rating
They are not only for the young and fit or the busy frugal employed.

They are also the answer for us seniors, who are bored with 'get fit regimes' and painful muscles and bones.

I can't walk very far, maybe half a km, but on an electric bike 20 k's (with hills) is regular, 3 days a week.

The biggest worry for us when we go walking out the door is "are we sure we can get home again (PAIN)"

There are 3 main electric types. I have been on them all.

1. Hub types (motor in center of the wheel) VERY easy to fit, no upkeep, get on it and go, just charge the battery.
2. Pedal crank (motor via chain to pedal crank), the motor is usually mounted on some sort of home made bracket, complicated to fit, and will eventually tear itself off the frame or will require constant tinkering to keep it going after 6 to 12 months when the chain sprockets go out of line. (I want to get on and go, plenty of other toys to tinker with)
3. Motor via engineered gearbox to pedal crank, very expensive and do require maintenance.

Hub motors are without question the best option from my experience.

1970s vintage bikeReview by Valentin Muenzel

Overall Rating
Initially, the idea of converting an original 1970s vintage bike to electric seemed a little wacky. But after much less effort than anticipated, our revamped bike with the 250W kit now runs absolutely beautifully. The range is fantastic, the ride so enjoyable and the savings from car parking will pay back the upfront cost within months. We highly recommend it! (Posted on 3/01/2012)
