G'day All
I have been lurking about the forum for a month or two now gathering information for my own e-bike build, a BIG thanks to several members that have been extremely helpful I thought now i have most of the info together I would start this thread so others may possibly have suggestions that might benefit the build
I plane to construct a custom frame, a trike frame, I am disabled (in-complete paraplegic) thus your standard two wheel bike isn't a possibility, pedals on this build will also be absent (i had originally planned on pedals but on further thought well.... ) So interest might be lost by alot due to this never the less we shall push on I guess you could call this my own custom version of a mobility scooter as we often see the elderly getting about in...although im not that old (39)
Thus far I have penciled a design (not to scale) on paper, apologies i don't have the skillz for autocad, anywayz...the proposed frame/drivetrain design-->
I was after a 'pro/stock' look, a lower seat height is required so as transferring from my wheelchair to the trike isn't a major issue. The frame will be constructed from thin walled mild steel pipe ranging from ~50mm to 25mm diameter (wall thickness ~1.5) I have yet to purchase all the piping required that will happen this week.
Front forks will also be custom made-->
Using the following plans
Electrics.
I have ordered the following from TNC Scooters
1000W Motor - 48 Volts (Model: MY1020)
11 Tooth Dual-D-bore Sprocket For #25 Chain
80 Tooth Sprocket for #25 Chain
48V Controller (Model LB37) Yi-Yun Brand Controller
Brake Leaver with Brake Switch
#25 Chain (70 Links)
2 Wire Ignition Assembly
Twist Throttle Cable (Hall Effect)
(and few additional components as spares)
From Cycle US The following will be oredered-->
2 x 20 inch x 4inch wide rims (had planned on steel 20's but they seem to have been removed from the list on the site ;-S (will email and see if they are still available.) along with 2 x tyres and trike hubs
Front wheel/tyre combo will be of the 20x 3inch variety sourced locally.
Powering the 1000watt motor will be four 12 volt 17aH SLA batteries. down the track i will go with the newer technology but due to cost (im on a disability pension) to get up and running SLA will be used The trike will be used predominantly for local runs on the bike path/footpath to the shops (approx 1km away) and longer runs to larger shopping center (and local pub hehe) some 3 kms away so the need for huge distance isn't of a big concern at this point. What is is hill climbing ability i live in a VERY hilly area. FYI it will be my only form of transportation, currently i wheel everywhere or catch taxi.
I have already purchased a 130amp mig welder ( i was a welder before my accident) and a pipe bender (awaiting delivery) to construct the trike frame. I have a pretty well equipped workshop at my home. This build will be a somewhat lengthy affai, that said i am hoping to have the trike complete (ridable maybe not prepped and painted) within 3 months.
OK..think that is about it for now shall post updates as the construction progresses
I would appreciate/encourage any constructive criticisms by members and thank those who took the time to read this thread
