Had lots of fun recently building these for a customer.  He had these German made Velomobiels (that is the correct spelling) shipped to us so we could install a couple high-powered electric bike kit setups on them.  Over 1000 watts of power and high 20’s mph for speed.  These are custom made with a full package of lights, blinkers, etc.  The customer registered them with the DMV as a motorized bicycle, which anybody can easily do and should do if your E-Bike goes over 20 mph but less than 30 mph.  He brought a trailer up from Southern CA to pick them up and sent me a quick note when he got home: 

“Once again thanks for a great job Doug. Wife took her first spin around neighborhood today. I wasn’t there but she said “it was fun”. I couldn’t have asked for a better response!”
