ADO D30C / DECE 300 Dual Motor AWD eBike Powered by KirbEbike KIT

I have never seen until now a KIT that is so easy to install, comes so well equipped and is so greatly documented. You get everything you need to install it, even tools, while the selected parts are really chosen smartly.

Frequently Asked Questions

Our kit is suitable for most bicycles, but please view the below details for reference.

Firstly, a 36v 250w front motor system is installed on the front fork instead of the bicycle's front wheel. And its dropouts are 100mm. So please confirm your front fork dropouts is 100mm. Please click Dropouts and view the video of the Dropouts measurement.

Secondly, please choose the wheel size, we have 20" 26" 27.5" 28" 29" 700C wheels. If you are not sure which wheel size fits your bicycle, please click the wheel size to check how to confirm your bicycle wheel size.

At the last, please choose the battery you like. Here is a short video about the installation of the downtube battery and rear rack battery. 

Please contact us at support@kirbebike.com if you have more questions.

How Far Can I Go (Battery Range)?

36V 13Ah battery has 30-40 miles of range
36V 16Ah battery has 38-45 miles of range
36V 18Ah battery has 42-50 miles of range
48V 13Ah battery has 40-50 miles of range
48V 16Ah battery has 50-60 miles of range
48V 19.2Ah battery has 60-70 miles of range
48V 21Ah battery has 65-75 miles of range

All figures are in pure electric mode, the actual mileage will be farther if there is pedal assist.

LG cells are better in product quality and stability, so the price is more expensive.

Excellent clean Product

Excellent clean well thought out kit with a very lightweight small front hub and small discrete controller,
I like the fact you can disconnect the wheel easily with a waterproof connector near the wheel. Performance is virtually the same as my off brand 500 watt with ac36v battery, I expect a 48v battery will make it fly!!!!

My first custom Ebike build using this kit...

It blows away any factory-built 250-watt kit I have ever tried while keeping a low profile of being the same size as a 250-watt still! The kit was straight forward enough to install, it's very comprehensive with an included toolkit
& brake sensors for both hydraulic & cable systems, most kits
do not include hydraulic sensors you have to buy them separately usually, you also get pedal assist sensors for Shimano square tapered bottom brackets & older design cranks so it covers all the bases. The 48v 20ah battery has very good range, I got 60 miles on my first charge with 1 red light so 25% charge still. It's definitely the sweet spot sitting in between the 250-500 watt hubs, I am very happy with the overall build quality including the wheel's finish to the components, performance & range, my Ebike journey has only just begun long may it continue :)

Great motor for my Scott mountain bike

WARNING to Shimano owners: you need to buy the lower bracket tool to remove the original pedal bearings. I messed up and got all excited that i could get my motor installed the day of and then ran into this roadblock and had to wait a few extra days for the tool to arrive.

Fairly easy install

Great product, easy to install, all you need is a tool to remove the bottom bracket, some allen wrenches and enough patience to watch a few YouTube videos. I simply bought some small coupling clips and rubber washers to put on the 5/16 bars so the frame can't slide off of them. I also got the 860c display, which I am very happy with and highly recommend it.

Highly recommend this one

This motor is just perfect for my car! Great performance to get me up hills, and a great installation manual that makes everything very clear and straightforward!

👍's up (:-)

I fitted the kit to my Raleigh Stowaway though the cable to the display, brake levers, thumb throttle isn't quite long enough and the motor cable is around a foot too long. I had a display cable from another build and found a motor cable on ebay that was the perfect length. I like that they give you a choice of two types of cadence sensors. The controller is a 36/48v 17ah and it comes locked to 15.5mph, unlocked 21.4mph

E-Bike Conversion Kit

Kit arrived as expected 2 weeks after ordering.
Battery finally arrived after sending an email reminder that i had still not received the battery within time scales after the kit arrived.
The kit was fitted to a trike bike. therefore a bit of forward thinking was required where to locate the controller unit as one of the cables could have been slightly longer by about 8-10 inches to allow a suitable fitting on the rear of the frames near to the battery for example.
took about a day and a half as needed to make a fitting bracket for the battery to be located and secured within the rear basket.
In all, a neat job was carried out and the kit works as described.

Great Upgrade

I'm a Kirbebike kit upgrader from Swytch kit, which has been great!
But this kit has taken me to another level.
2nd journey out yesterday, went further, faster and furious!
Brilliant fun...
Worth the spend!

I’ve only received the battery and not the e-bike front wheel conversion kit ? :( not received full kit. I’ll update my review once I received the full conversion kit.

would it work or blow up?

Can this kit be used with a 52V 15A artery or would it need a different control unit?

350w Front Wheel - First Ebike Experience

Took around two weeks for all parts to arrive. All parts appear to be decent quality. Wheel is nice, much better than i expected. Pdeal assistance sensor is quite difficult to place, this may just be my MTB due to the limited space. Whilst the video was helpful, it took around 2 hours to fully install. Throttle option is a nice option to have, however on my first ride of about 2hrs it was not available to use towards the end of the ride (i assume the controller got to warm). Second ride which was about 1hr 30 mins there were no issues. However, i was advised not to put the controller in the bag whilst the weather is warm. A bit of a strange comment, surely more people will be out using it in dry sunny conditions. Maybe, it should be considered that a winter and summer controller bags are provided. Overall, very good value.

High efficiency kit

I needed a low power front wheel kit to give me more range and a little extra pull on steep hills with my 250 watt mid drive motor. This 350watt kit delivers perfectly.

Works great and less expensive than alternative

Battery was bought for 750w conversion kit. Works great. Battery will last over 20 miles without much pedaling. The company will send the power adapter for your specific motor upon request.
