-You will have to do all of the following yourself:

  (1) Manually file the vertical dropouts in the frame to fit the large 16mm diameter X 10.8mm axle flat of the Cromotor

  (2) build the passive heat sink (1/8" 5050 aluminum plate)

  (3) modify the trunk bag to house the controller (3/16" ABS sheets)

  (4) build the battery boxes (1/4" 6061 aluminum bar and 1/8" angle aluminum)

  (5) modify the panniers to house the battery boxes

  (6) make and fit the torque plates (1/4" 303 stainless steel plate)

  (7) change flat tires in the rear

I used a machine shop for my rotor spacers and the D-hole in the torque plates.

-Be very picky about what mechanics and, to a much lesser extent, parts suppliers that you use. Having a knowledgeable, professional electronics technician and bike shop is a very nice thing. If someone gives you trouble, move on and don't look back.

Having just completed the two new bikes, I recall that the ten months it took was very expensive, time consuming and challenging.


I needed to have countless experts come up huge in their expertise to get me through it. The amount of money that I had to throw at the project was shocking.  I had to redo several things when I was broke and exhausted.  I definitely was running on empty a lot of the time and frustrated almost to the point of crying on countless occasions.


Having endured these challenging times, I ended up learning a great deal about electronics, bicycle mechanics, welding and materials so it was all worth the effort.  The journey, however, was rough and challenging rather than smooth and fun.​​


Of course, riding the bikes is always fun, and I am definitely acquainted with every inch of the machines.  

-I have found competent, professional specialists who do the following:

  (1) electronics technician

  (2) hub motor wheel builder

  (3) LBS who is willing to work on e-bikes

I like to have as many sets of eyes as possible on my high speed bike (for safety reasons).

-Getting quality parts and service is expensive and can take a long time, but it is worth waiting for. It would be impossible to build a bike like this in less than 5 months--plan on about 10 months. Building a bike like this will set you back about $9,000 and the security measures that should follow it are another $1,000.

-Be patient and willing to redo something again and again until you get it right. This can be an expensive hobby; I made huge sacrifices in my other expenses.

My original battery had a 50A BMS on each 36V battery (in series). I found myself drawing up to 81A, so I put a 100A BMS on each 36V battery.

I no longer make new ebikes, but I am having a very fun time riding, repairing, maintaining and fine tuning the four bikes that I have. I am investing in bike and electronics tools and learning how to fix every aspect of my bikes.

Over the next three years, I will be attending 54 days of bicycle mechanic and frame building classes at United Bicycle Institute in Portland, OR.

Here are some things that I learned the hard way
