Thru Axel vs Quick Release. What electric bike conversion kit works for each?

When it comes to securing the tire onto the frame there are many methods available to bikers, each of these methods hold advantages for their particular applications and in this article, we are going to look at Thru Axle and Quick release mechanism and try to identify their strengths and weakness along with a discussion on which axle works best for electric bike conversion kit.

 Thru Axle - Envo drive systems Quick Release - ENVO drive systems


The tradition approach for securing wheel with frame was to use a solid axel with bolts but this method had a lot of limitations like difficulty in replacing the wheel. Over past decades quick release mechanism coupled with bike dropout has largely replaced this method.

The advantage of quick release lies in the ease of usage, the slots in the frame allows for the quick alignment of wheel. Additionally, the time it takes to secure a wheel with quick release is substantially less than other methods. Additionally, it is easier to find a replacement parts if need be and the cost is substantially less, the weight of the quick release is also less than its competitors. The strength of quick release is more than enough for urban and most off-road applications.

 


The thru axles are stiffer, stronger, and hence heavier than their quick release counterparts. Thru axles use holes instead of slots and the axles goes through these holes and wheel to secure it to frame. For most users quick release does not have any serious disadvantages but for high performance users specially mountain bikers the failure rate becomes high due to added stresses caused by disc brakes and suspension forks, it is for those customers thru axle holds biggest value proposition. The biggest issues with these are higher cost, heavy weight, and difficulty to find a replacement due to its specialized construction.

Thru Axel vs Quick Release, which is better for conversion kits?


The hub motor conversion kits are generally only compatible with quick release mechanism due to the dropout slot present in the frame. The hub motors are secured using bolts on each side which is not possible in the case of thru axle configuration. You can refer to the assembly instructions for ENVO hub conversion kits attached below. Hence, front hub or rear hub conversion kit configuration may be influenced by the presence of slots on the frame. If the bike frame only has holes for thru axle then you may want to use a mid drive motor conversion kit instead.

Sorry James you got it backwards, the quick release has the slots hence why it is quick… And the through axil goes through the holes hence why it is stronger!!!

I believe you have confused the through axle and quick release axles in the explanation. A through axle is a solid threaded axle and has slots in the frame. The axle is slide into the slots and held in place by nuts screwed onto the axle ends. The ebike motor axle is prevented from rotating due to a washer that has a raised ridge which prevents it from turning in the slot in the frame.

A quick release uses a skewer that goes through holes in the fork. There are no slots in the fork frame for a quick release wheel mount. The wheel is put into the forks and a skewer then goes through the holes in each fork hole and is secured by a thumb nut on the end of the axle.

The article leaves me confused as to whether the motor is compatible with the old style solid axles. I currently have a 36/48 volt 500 watt front wheel kit that slides into slots in the forks. Have a second 3 speed bike of the same model and make I want to put a similar kit on so I* can use one of my 36 volt batteries on it.

It looks like I’d have to cut off the round battery connectors and crimp on square battery connectors to be compatible with my batteries. A 20 amp battery (10 cells in series X 6 cells in Parallel) is the minimum I need for bicycle snowplowing and towing a bike camper. Typically I only get 30-35kms running full power (no pedalling) with two 36 volt 11.8 amp batteries.
