Cool, hopefully they keep the prices reasonable. The picture looks like a stock unit. I would like to see what modifications they did to the brackets to prevent torque twisting.
I feel like this kit has a lot of potential. With the right after market parts to fix some small problems it could be great. My only worry is the gears. Are they easy to replace? Are they cheap?
Really excellent work here. I designed something similar for myself last year but it never got off the CAD page. That sprocket must have been very difficult to manufacture. I designed my part to work with replaceable sprockets like the one in the picture. A plus is being able to change...
BB sizes are certainly something I will be addressing in the future. The future for now is designing a basic system that works and then worrying about how it will fit all the bikes. I can not divulge any more information about what future plans are.
Just noticed you replied. I am going to try adding that resistor from the green wire to THI.
I am wondering how adding that diode could work. The way I understand it is as soon as EBK goes low it overrides anything that THI says and inputs the low throttle out voltage that the user programs...
I will be straight with you. This kit is not as quiet as the BBS02. It is designed to run 4 times as much power. The kit is relatively quiet when used at 50 volts since the belt, chain and motor are running at a lower RPM. The problem with that is that at 50 volts you are limited to 2000...
It keeps the bike itself lighter and more easy to maneuver. Going from a 3 litre camel pack to a backpack battery pack is not a big leap. Many people who mountain bike carry backpacks. Anyone who has been downhill biking knows what I mean. It took a little getting used to in the beginning...
It is not difficult at all. It is quite comfortable. It is not like I am exhausting myself from pedaling up a mountain here. There is no pedaling involved. On trails having your battery in a backpack allows your bike to be more nimble which is important.
Ill be posting a few short videos in the coming weeks. I only just got a GoPro myself! I was in Kelowna (mountainous and warmer part of Canada) in late February testing my prototype so I know it works great. Now I am back home in Edmonton and there is still snow on the ground! It is also...
