So how did you widen the cranks?4 stroke in the frame? Hmmm seems like I've seen one of those....where was it....oh yeah! It's in my garage!
Does anyone sell cranks that will fit onto a modern bottom bracket?I have the Grubee 1 piece widened crank and I used it at first, but then I switched to a short crank from a 16" kids bike. It does not rise high enough to interfere with the engine mount.
Actually, it is more accurate to say it clears the mount on both sides (by about 1/4" on bother sides, but is not long enough to hit the engine shroud or gearbox.
According to Sheldon Brown's (RIP) Online Gear Calculatorlook at that pic above for a second and tell me whether I pedal much.
To each their own, of course but the answer to that question is the reason I won't mount an engine in the frame.i have no idea what is a better engine (4 or 2) but it seems only 2;s are put in the frame .. why is that? i dont care for the rear mount style.
Cool, I must admit that's a clean looking install, high and tight. So you were able to keep tread distance the same as original then?There are solutions for virtually every cycle and bottom bracket set up. I have 3 piece on my mtb that utilize the original bb but w/ only 1 fr sprocket. I understand HV what you are saying about the componantry but can't stand the idea of putting more weight directly over the rear wheel; if I do a rack job it's goin' on the front. But the best place (physics wise) to distribute the weight is in the frame, low and center.
