I bought a cheap motorized Nel Lusso a few weeks ago, and have enjoyed the heck out of it. I am now looking to build one myself here soon. I'm willing to invest a fair amount of money into this project but I also don't want to waste it either, which is what has brought me here. My plan is to get the Micargi Stretch Beach Cruiser GTS https://www.bikesxpress.com/Micargi-Puma-GTS-Chopper-Beach-Cruiser-Bicycle-26_p_75.html , replace the stock tires with 26x4s, and install this motor kit. https://www.gasbike.net/products/thunder-shark-pro-racing-66cc-80cc-bicycle-engine-kit-5-0-hp I'm pretty set on sticking with a 2-stroke, though I am willing to listen to counter arguments. My main concern here is the motor kit. From my limited knowledge on the subject, it looks and seems like a good kit, pricey, but quality nonetheless. If I'm wrong though, please tell me. I'll be using this bike mainly for road travel as I live around a small city and plan on making it my work vehicle. The area is a bit hilly, though not too bad, and I only weigh around 160. The bike I have now I believe is a 40cc and while it slows down some on hills, it otherwise works just fine. I am looking to get a bit more speed though and a better quality engine as my work commune is a 20 mile round trip and is currently taking me about 40 minutes each way. Any advice or suggestions would be greatly appreciated. Thanks.
