hi
If you're looking to go about building a motorcycle disguised as a bicycle you're in the wrong thread.
My goal is anti-thesis to the somewhat-normal bicycle build on ES
My intention is to use a similar two-motor system as I used on my EMoto Trike which came equipped with a front geared-hub motor and rated for 250w. As the EMoto Trike is a standard delta sit-up-high tricycle, it's very unstable when doing sharp turns.
As such the designers of the EMoto saw fit to limit its' top speed to 8 MPH which is (in that Martha Stewart voice) "a good thing"
After riding it around town I rapidly discovered the Trike lacked *any* hill climbing ability. bogging down on the slightest slope. And folks, where I live there's LOTS of slopes. Some slopes slope-ier than other slopes.
So after some thought, considering the limitations of an upright delta tricycle I decided to add an additional motor.
The front motor for normal operation and the additional motor for climbing slope-ier slopes
I use a pedalec 'throttle' for the front motor and a half-twist throttle that came with the EMoto but reassigned to the other motor's controller.
This has proven to be an excellent solution when using a geared hub motor that's just sufficient for operation on flats and climbing moderate hills with 2-8% grades thereabouts.
now-I also intend to build a roof of 4watt solar cells and enclose the whole trike in a structure of fiberglass tubing covered by a coroplast/vinyl bodywork.
-this part of the project is dependent upon weather for a completion date, as the work will have to be done on my (outside) pic-a-knic table
I purchased a Belize Tri-Rider Semi-Recumbent Comfort Tricycle (try saying toy toy toy out loud really really fast) via the Jazzysports online vendor (so... jazzed)
I suggest no one should buy this Belize piece of work unless you're willing to invest the time, effort and money needed to turn it into a semi-viable vehicle. I did but my needs are different than the below average remotely healthy individual.
I suggest the Terratrike Rover with an 8 speed hub as a suitable 'economy model' base trike, if you want to pursue such a project, but I lack the physical dexterity needed to operate that particular model or any 'real' recumbent bike or trike.
From what I've experienced, using a pedalec-controlled front hub motor fed it's own battery and a 'hills-only' motor fed from a different battery begets a very efficient electric-powered vehicle.
Doing some research for a different reason I stumbled on the fact that there is a saturation of solar panels and cells in today's marketplace, and (unlike gasoline) has depressed prices to 'cheaper than the batteries they feed' ...
However, for use on a tricycle meant for bike lanes and such means narrower (and lighter) than what I can find manufactured, so I'm having to build my own panel(s).
Building your own solar panel is currently NOT less expensive than buying pre-built panels (just like building your own e-bike isn't cheaper than just buying one)
The solar panel is not something I'm looking forward to building, as the roof size is calculated to be 30-something inches by 6 1/2 feet long x 2 panels
I estimate the panels should produce about 125 *real* watts (peak rating of some 330 watts worth of cells)
I intend to use this vehicle to regularly cruise 25 miles one-way but I only intend to carry a 36V@15AH battery for the front motor and a 36v@5AH battery for 'dem hills'
oh
and no cad from me
sorry
I had to use various cad systems for work from 1985 up until I retired and realized how much I don't miss it.(i.e- no fun no joy I ain't doing it no mo')
+it's too simple a project to bother with
...anywhoo this project is currently calculated (with me occupying the seat) @ 375lbs thereabouts
-will update this thread as I receive the various parts and successfully attach them
comments are always welcomes even I forgets to properly acknowledge them
- hey- I'm old and forgetful- and basically :? confused, as old people are known for being.
oh
and jokes are fine, too
