I need help with initial planning and project development.
I would like to build an EV bike.
I am a skilled mechanic with access to many venues as well as parts and tools for fabrication.
The range I'm hoping to get is really my least concern. Minimal 20-30miles max would be satisfactory. If we can get more then all the better.
The level of performance *I am hoping to get* is a minimum equivalent to a 220hp ICE engine, preferably high revving (10k-14k RPM's). I understand that electric motors, especially DC are renown for their torque. But please do not make under-power recommendations for my my goals. Basically, what are some motors that are relatively close to the value of the ICE engine power I want (+/- 10%). It's hard for me to say as Ive seen people claiming that the hp isnt a direct conversion due to inherent torque delivery differences in each form of locomotion.
As I am under the impression that DC motors are more torquey - I find myself leaning heavily in the AC direction. As most can deduce a sudden burst of torque will throw the bike into a wheelie. This is not my goal. I am thinking a max weight of 800lbs overall (+/-10% - the bike, motor, battery and controller, etc.) which should help with any wheelie problems however I still need to fairly accurately control the motor speed. Needless to say, I'm not a fan of road rash.
How much money?
Well lets put it this way - Im not a Bimmer driver from Croatia (but props to his EV bimmer build, amazing; in concept and cost.)
Simply put, I wont put a fortune into new parts. I mean I could but the more you spend the less enjoyable the outcome is. Id rather put more work into the final project than money. But I wont mind if you offer some realistic numbers as to what to expect to spend or even a range to help me decide. From questionable quality to good, used, or even new quality.
This being said, in case your all wondering, I do have a background in electronics. Unfortunately it's almost all analog experience. I do have Logic gate experience as well as some in building amplifiers (no, not installing car audio - give me some credit.) and other simple digital devices and micro-controllers. So, sure I could pille up a bunch of dry cells from autozone with a huge frankenstein style potentiometer, or some high power transistor - mount it to a bike frame and putt about getting absurdly poor performance and even more absurd looks. But that's not what I really want to do.
I'm looking for 4 main things.
Value, used parts I am ok with - but this is not a junkyard build, no hoopdi
Simplicity, even if it requires me fabricating things, this I Excel at.
Control, an accurate motor controller I can rely on, but not made of gold.
Power, 220hp equivalent - crazy torque not required.
Coherence, the bike needs to flow, no quirks or regular issues. I want this to be a thorough build.
All the rest such as looks and mounting will be directly resultant of the drivetrain and its components. This is not a concern for right now. After all - form follows function.
If anyone has the knowledge and experience to see where I should be headed and with what - it will be greatly appreciated. Ive had this idea eating away at my imagination for some time now and its time to bring it to life.
I will continue pouring through the incredible wealth and volume of information on the DIY wiki pages, and hopefully I will hear back from people. Thanks ahead of time, and props to this sweet forum.
