We recently had the opportunity to build a fully custom Electric Road Bike for Rolf Dietrich, founder of Rolf Prima wheels, a renowned premium wheel deign and manufacturing company that has been building high end cycling wheels for many years. Rolf has ridden hundreds of high end bikes and seen many handmade titanium bikes in his long career in the bike industry. It was an honor for us to be chosen to build his custom e-bike.
Zinn Custom E-bike review
Lennard:
   Thank you very much for that forthright answer. I did notice the difference in the surface finish of the motor cradle between that of the tubes. I’ve never seen a 3D printed one and from your description I appreciate that you resorted to one with its advantages.   Without doubt, Nalby’s welds are the absolute best I’ve ever seen and that you’ve worked with him all these years reinforces the confidence I had in choosing you to build my bike, along with your prior build of the Mg bike for me years ago and your long experience as technical writer/editor for VELONEWS.  By now the accumulated mileage on my ZINN Ti e-bike has reached 300 and I’m enjoying it more with ever ride. According to Nick you too enjoyed riding it on your test ride which included my 16 spoke wheels which are currently still mounted on this  40 LB e-bike. As you know, with e-assist, weight is no issue and I ride routinely 50% faster than without an e-motor & the heavy ROHLOFF transmission.  One of these days when I’m visiting relatives in the Denver area I’ll have to bring some 16 spoke ROLF wheels with me and drive to your shop to have you try them on your personal bike. Speed is my thing, still, even at 83 years of age, and these will make you too faster!   If you would, please thank Nalby personally for me for his outstanding welding on my bike.Thanks,
Rolf
