1500W Electric bike kit - High capacity, long range battery

Our latest iteration of the popular 1,500W rear hub motor kit features some very significant upgrades. This kit comes with the new Dillenger 17.5Ah long-range 48V battery system. This makes it possible to mount 840Wh of high-performance battery within a bike frame, without the need for sloppy soft bags (no thanks) or custom fabrication. This battery system makes it possible to house a lot of energy in a safe, rigid and stylish assembly. Say goodbye to range anxiety with 48V 17.5Ah packaged neatly within your bikes standard shape frame. A new sinewave controller accelerates your converted bike effortlessly without any noise whatsoever. It's an astonishing feeling that is highly addictive!


Product Description


Plug and play

The original 1500W kit was without a doubt the most 'plug and play' fun you can have on a conversion kit when it was designed, however customers didn't always know what to do with the huge brick of a Samsung pack. We spent a lot of time (longer than we would care to admit) experimenting with ways of carrying around 800-1000Wh of 18650's. The weight and the volume of the cells are the key issues. The weight is considerable compared to much smaller packs, which means the weight should be located both within the wheelbase and near to the normal center of gravity. The volume of the pack makes that very difficult given the broad range of bikes out there. We took the most popular frames that our customers convert and designed a cell pack and case that are compatible. The location of the pack and the way it mounts universally makes it extremely compatible for any hard tail design (and some large dual suspension frames).


Why did we stick with such a large pack? 48V 1705Ah is not a large battery for 1,500W of power. It is adequate. Too little and you will come up short of an ideal range, too much and your bike will weigh as much as a motorbike. Range anxiety can mean the difference between trying new trails and sitting on the couch so we decided to keep the capacity the same. The long-range battery adapts to your bike without modifications to your frame and includes enough battery to get the most out of this system.


If you'd had the displeasure of mounting heavy things in soft bags and then trying to ride hard, you'll know that soft packs are not an option (without even mentioning the issue of safety and protrusion damage). Riding with the Dillenger 17.5Ah battery doesn't feel like you're carrying double the normal amount of battery. The center of gravity is almost unchanged. Tipping the bike into corners and maneuvering over rough terrain is no issue. With the battery installed, it still feels like you're riding a mountain bike, not a bag of bricks. Rigidity is key for control and the battery fixes to your frame firmly and safely, while still giving you the option of charging in situ, or removing the battery without removing the mounting system.


When we sat down to organise a redesign of the 1,500W kit, we didn't take any ideas for granted, we even thought about RC style Li-po's with a BMS. In the end, we kept the pack construction using genuine 18650's because they're a safe, reliable and last the test of time. This kit is a large investment and although it's denoted as 'high performance' we didn't think that should mean that the longevity is any different to our other conversion kits. This kit has the same safeties in place and the same warranty as a lower output 'street legal' kit. So you can be assured of the longevity of the kit, including the battery and charger.

I bought the older brother of this kit in July 2018 so it is, I think, the 1000W Bafang motor.
Dillengers put this Samsung Powered Premium Off-Road Conversion Kit on my new 2017/2018 Trek Marlin 7 ( 29er ) Mountain Bike. A few teething troubles, like the controller burnt out, but since then all good and, I must say, she goes like a rocket ! (Posted on 16/01/2019)
