A few questions.
Are these specifications correct?
Are there better or more common specs (would 4 bolt be better)?
What size electric brake assembly would we need?
What would you recommend for a good brake controller for a Honda Element?
Hi Guys, I would really appreciate your feed back on these specs. The fellow building my frame wants to get it done before the years end!!!
Hi Dave,
I've been checking your specs. For my comments below, please keep in mind that I'm a well-wishing amateur. Hopefully the experts will chime in.
These are my thoughts:
1. In your frame drawing, there is a conflict for the dimensions of the frame width. On the right side, the o/o dimension is 56". On the left, the individual dimensions total 57". By your axle spec, the 56" dimension appears to be what you are wanting to do.
2. There seems to be one axle spec that is missing. That is the hub face to hub face dimension. From what I found on the flexiride spec, the overhang distance from outside of frame to hub face can vary from 6.12" minimum to 10.25 maximum. I "clipped" the drawing below from the flexiride website.
Your tire section width will vary somewhat depending upon what width wheel that you use. From a chart I found online, a P205 tire on a 6" wide wheel has a section width of 8.23".
Assuming you spec the minimum overhang of 6.12", with a tire section width of 8.23" and a wheel offset of 2 mm, I come up with the inner edge of the tire being about 2" from the outer edge of the frame. (clearance = 6.12" - 8.23"/2 + 2mm/25.4mm/inch = ~2.0")
The 2" clearance will leave room for your sidewalls to extend below the frame if that is what you intend to do.
3. The distance from frame to outside edge of tire is 10.23 inches. You may want to want to think how these dimensions affects your fender width. Assuming you use 11" wide fenders, the fenders are flush-mounted to the sidewalls, and the sidewalls extend beyond the frame by 3/4", then the clearance between the fender and outside tire edge would be about 1.5" less the thickness of the fender.
Please double and triple check my numbers. From what I understand from other posts about the flexiride axle, you can provide them with your dimensions and they will spec out the axle.
Sincerely,
Tom
