Here is my dash with the speedometer, LED headlight, and battery meter.
I chose not to install the cutout brakes because after riding for a few days, they were just in the way and useless. I unplugged them and just let off the throttle if I need the motor to stop. This may not be the safest thing, but oh well.

Leave some comments and any improvement ideas. If you want to know how I hid the wires, I used a short section of the rubber used to cover power cords on the floor with a pice of foam rubber on the back.

Forgot to mention, even though this has an aluminum frame, it does have steel forks.
Top speed - 24 mph downhill
Avg speed - 20 mph on flat
uphill - 10 - 15mph depending on peddling

Nice conversion!  ;D

I installed standard baskets to carry larger batteries but the lower center of gravity actually worked against the idea. Batteries above the rear tire makes control a lot more responsive.

I also built a battery carrier out of 1/2 inch EMT conduit for less than a dollar using fasteners and other stock on hand. It required a stick of conduit, 8 machine screws with washers and nuts, 2- .5" pieces of 1/4 copper tubing, 2- 2" x 2" ,12 to .16 flat stock, a hack saw, a ball-pean hammer and a drill. Batteries will be upgraded and moved to a small trailer now in the works for heavy loads.

The local shop had one of those seats for $44.40 but my back can't take the shock compression anymore so I'm looking for a recumbent seat conversion.
