Hey Guys,
No, I am not being arrogent. There is a reason for my thread title that will become apparent soon. This should be a very fun thread, not just for the build itself, but for the banter back and forth. This thread should add some spice to the forum.
Now, here is a description of my build;
Frame--- Qulbix Raptor 140 with 150mm dropout spacing
Drive--- Multiple Astro Flight 6 turn Delta 3220s with belt to jackshaft and chain to wheel.
Controllers--- Edge 160s
Cells--- Lipo (12s 40 to 60ah depending on how many I can fit in the frame)
Forks, wheels, brakes, tires? Not sure on that. I will be obtaining parts as I can afford them.
This bike will be running either two or three 3220 motors. I have eight of these motors in the shop just sitting around (yes, you heard me correctly, I have eight 3220s sitting here, and 7 Edge 160 controllers that are unassigned to any particular project). Many of these are used and some are new.
I have all the parts in stock to build a twin motor drive and a triple motor drive. There is no real cost for me for that part of this project.
I am sure most of you will say "Just go for three motors". However, there is much to be considered. A triple motor drive is heavier, less efficient, and a handful to ride. But, we are talking ENORMOUSE power! Three 3220s would be capable of 40,000 watts of peak short burst power with a continuous output of 20,000 watts. This would be great for deep snow riding with 50mph final gearing. But, the range of the bike would be less than desireable. A twin motor drive is lighter, more efficient, smaller to package, and still has tons of power expecially if geared for 40mph top speed. Maybe I will build both and try both. We shall see.
This build began 18 months ago when we (my partner and I) ordered this frame for prototype testing for a potential production bike. After sand blasting the frame for modifications, that project was scrapped and the frame sat idle gathering some surface rust. Then I built my Motoped with two 3220s. That bike was nearly perfect for high power riding. But, it looked too much like a motorcycle. That made is less than stealth. I have since wanted a bike with that same power while looking at least a little bit like a bicycle. The Motoped weighed 147 pounds. I hope to have this bike weigh in at 100 pounds. That weight savings with twin motors will make this bike awesome to ride without being so sluggish in handling.
This frame became available for my use when my partner and I separated. He got the checking account and I got the entire business, web site, and all inventory. Win-win!
Now to the technical info;
The drive will be mounted under the frame box with a removeable cover to protect it when running in snow (VERY fun riding a powerful E-bike in snow!). The box needs to be modified to accomodate the correct chain line. This will become more obvious as the build continues. The 150mm dropout width was ordered because, as a hub motor designed frame, that was the only spacing available that I could find an off the shelf hub for. So, I bought a Kore 150mm wide rear hub designed for a 12mm axle. The dropout slots are 10mm wide. So, I will use a 10mm axle with a 12mm to 10mm reducer inside the hub. This solves the hub motor to mid-drive dropout difference issue relatively easily. The rear rim will be a very wide (not a fat bike rim) 24inch downhill rim and I will run a 2.5 to 3 inch wide rear tire. This is what the Motoped came with and it was light, but had a motorcycle stiffness and traction I like on a build like this.
I hope to have this bike up and running before the snow flies. I figure I have about 20 hours of frame work and custom machining to do, then about 8 hours if wiring and building to do. That should not take too long. Assuming I can raise enough money to buy the remaining parts I need, I should have it running in two months.
I am leaning toward yellow powder-coat on the main frame with black carbon side panels and all other parts in black. Maybe I will call it the Wasp? Hmm, have to think about that name. Anyway, I like the idea of mostly black with a strong presence of yellow. It will have a little bit of Yamaha flavor to it.
Let the fun begin!
