Don't worry, I can fix it. I got my exercise already. The bike is a tank. It rides nice and the two speed hub works well, but I can already see it will get an engine. Probably the GC160.NO NO NO PEDAL POWER seem's to much exercise,but still a great looking bicycle

Here is the GC160 mount. These engines are rated at 5hp stock. Couple nice upgrades would give 6.5 to 7 hp. I know the chassis can handle it. Should make for a solid performing bike.
