I remember Safe. He is the man that all men wish they could be. Could prove anything with an Excel spreadsheet and magnet field graph. Could see and understand things that no one else could. :roll: Bubba

Cut the case out of 3/8 inch PVC. Got it all wired up and ready for a ride. One day I may make a new case for the Cycle Assist that will include the throttle. Bubba

Got the parts from Newark aka Element 14. The wiper of the five 5K pots are wired together. The 2 pole rotary switch is switching the power and ground to the 5 pots so that only one pot at a time is connected across 5 volts and ground. Next step is to machine a case for the rotary switch...

I used that motor on my first ebike. For batteries, I used small ridding lawn mower batteries. The weight of the system and the width of the motor makes what you propose better suited to a trailer pusher design. If you look back through the archives, you will find that the inexpensive...

Got the parts on order for the throttle, but could not wait to try it. Scrounged up some resistors and a limit switch to create a throttle on a stick. I like having it on the brake hoods. It is easy to reach and your hands are in a natural position. Bubba

It is all together and just about ready for the road. Still needs some handlebar tape and the final seat adjustments. I don't like the throttle. It can be used while keeping a thumb hooked over the brake hoods, but it is awkward. The throttle mount is made from an adapter for mounting a...

Well I had a brain fart when I ordered the rear hub with threads on the left side. I was thinking that the threads were left hand and I was going to use my south paw freewheel. Turns out they have right hand threads. Tandem hubs are a bit pricey, so I decided to buy a disk brake screw on...

No plywood on this build. This is an upscale build. :wink: I am using laminated 1/4 inch oak. On one of my other builds I sandwiched the wood between two sheets of aluminum. That was a mistake. Having that second piece of aluminum around the bell of the motor created eddy currents that...

That should have been 12s or about 48 volts. The seat does needs to be adjusted along with a few other things. The bike got to me too late in the season to do any ridding. I just quickly assembled it and went around the block once. The temp has to get above 65 def F before my wife will go...

I like upright bikes and my wife likes recumbents. Bought the Viewpoint to make us both happy. It has independent pedaling and gearing so it also solves the problem of me spinning the cranks too fast for the wife to keep up. The design is rack style motor mounting, left hand freewheel to...

Got all of the ebike parts together. Went for a short test ride and everything was working. I need to adjust the 2nd stage chain alignment and that is about it. Since I am using a twist throttle, I have ordered a bar end shifter to replace the twist grip shifter. The new shifter should be...

Finished the 12s 2p 10ha battery pack. Overlapping pieces of inner tube allow me to pull the balance connectors out for charging while keeping water out when running. The white case is 3" X 4" down spout with three braces that I milled out of aluminum. Bubba

I used duck tape technology to figure out where I am going to put the battery pack, controller and cycle assist. Bubba

There will not be anything new on this build. There is just a little CNC work in the end caps. I am using the stuff from the upright tandem. If I had the time, I would redo the rack and motor/jack shaft support out of aluminum. The picture is my new battery box that uses 3"X4" down spout...

Did you miss me? It has been a while. Life has gotten in the way of my biking. I use to ride with the racer boys, but this year I only got in 50 miles total. Hopefully next year that will change. Usually I procrastinate, but this year I am trying to get ready for next spring. My wife...
