Hi fellas!
This is my first post here (passed maybe months reading before thinking of signing in). Could not find any presentation board yet it's not the main topic So...
Let's keep it quick, I'm a frenchie student, almost ending my course in civil law and tax studies. I'm into car stuff usually but got really interested in e bikes since this summer because I'm amazed at how some of you guys here build stuff. It's almost like building a zero emission motorcycle with the weight and lines of a bike (sort off). That's where the interest started from.
Back on topic! I can craft aluminum and steel, wood, heck I have possibilities. I want to build a custom cruiser. I already have design on paper but need a lot more reckon on best parts compatibility and also good compromise on the frame materials themselves.
The starting point is either get a rear hub monster from John in CR or its little bro mid monster. Reliable power, efficient and polyvalent.
The frame is designed to be for e bike, so there is plenty of room for battery packs and controller, even mid mounting monster can be fit. I initially thought of making the main frame in 6061 aluminium for example and put solid steel rear / torque arms with rear suspension and a dirt bike front fork. Either going for fat tires and rims or dirt bike wheels if the first ones aren't strong enough.
Most of you guys prefer to go the steel and chromoly way but this is heavy. The bike is supposed to support occasionnally 140kg weight (no I'm not that heavy, I'm designing a 2 seater for my wife). I try to counter the heavy load with lightweight materials (car dude's logic). I also see that there is a Hoboy carbon fork which is light and strong. A dirt bike fork has the advantage of offering true frontal suspension but is this really mandatory? I see downhill forks too, knowing how much power a well driven hub like John's can deliver I wonder if the dirt fork is overkill or needed.
I can craft a lot of materials but of course nothing like carbon, I let this to Drbass. What do you recommend? Lightweight and strenght are main words.
Mid driven hubs offer gearing use, plain hub are direct drive normally. Easy mount vs somewhat better weight distribution and range of efficiency for power. Not the main problem, both hubs are designed the same way but different size. The other problem is : for a mid mount, what gears/pinions/chains are strong enough to withstand the hub's strain?
Honestly I have no idea about what battery packs are worth for, only that 22s or 24s lipos packs will match my needs. What do you usually use at this capacity level?
How reliable is it in time?
About controllers, I was thinking of using 2 Sabvotons controllers for a good sinewave control, good choice or you recommend something else? I remember PAS can be done with it, it is important because in my country we fall under the 250w power limit.
Thanks by advance for reading me guys!
