Hi all,
I've been thinking about building myself an e-bike for a little while now. I've done a bit of research, tried to figure somethings out. Honestly I realize that it's probably best to get some advice from those with experience. Please let me know if you think my plans for a build are feasible or not. Caveats you think I may have to deal with, or any advice you have to possibly offer.
Firstly my proposed constraints are: atleast 30-35 mph max speed, 70-75 mile cruise range, $2,500 Max cost
From what I've read, it seems that to achieve this sort of range with that sort of speed, I would need a very large amount of Ah, as well as a relatively high voltage. Unless of course the e-bikes weight was very low. I could opt for a aluminium frame in order to reduce weight potentially. Of course, I have very little frame of reference on those constraints and how difficult they would be to achieve.
Some ideas that have been floating around for a bit, would be to implement regenerative braking. An Arduino controlled system to measure my pedal energy input as well as throttle response and electronically select the proper gear. It seems that in order to make the conversion of both mechanical and electrical into kinetic energy most efficient. I should probably program something to optimize gear automatically, rather than fidgeting with it while riding. I'm also concerned about theft and security if I end up sinking a bit of money into this project, if anyone has any experience with anti-ebike-theft, advice would be much appreciated. Please do not hesitate to let me know if you think this project would be a bit too ambitious or even almost impossible to achieve. I personally have a feeling in the back of my head like it can be done, but I haven't built an e-bike before. I do understand that there are quite a few variables involved here such as payload (rider + whatever is carried with), energy expenditure due to environment, whatever frame would be utilized comes with its own constraints and issues, just to name a few.
I really appreciate your reading of this post, and look forward to any advice you have to offer.
Thanks,
Dyson
