![]() Don Grube says that his new kits will have the 48T as standard. Nearly all of us find it the totally wrong sprocket for the 11T freewheel drive and opt for the easily available 48T. I notice you have what looks like a 56T sprocket on your bike and, if so, I wonder how you can stand the extra revs, vibrations and slower speed. The crank doesn't look like it's much wider than standard cruiser cranks but I believe you when you say it's 6" wide. Your crank solution is only of use to someone who can access a Next bike and I have never seen them in Australia. They don't sell them in Australia that I'm aware of. Thanks for those pics Nsideus, the Point Beach Cruiser is pretty good for motorising given it has 2 decent brakes. I see that Bicycle-Engines.Com are still recommending the wet gearbox solution for the Grubee gearbox even though we all tried it last June and by July we'd practically all agreed that the lithium grease worked much better and all this knowledge is posted on threads right here for people to read. ![]() Incidentally it's worth spending an extra $5 and using heavy duty bearings with those 1 piece cranks because the leverage from the extra width really puts a lot of force on the standard bearings. I implore people to write to Bicycle-Engines.Com and express their concerns and ask for the 1 piece crank to be reinstated as standard in the kits. There are no 1 piece cranks available right now and the 3 piece is totally hopeless with shorter crank arms and harder to pedal etc not to mention its incredible ugliness. Whatever the reason it is a disaster and is costing us dearly. Maybe they hoped it would sell to people with MTB frames who wanted to try the 4-stroke. Don told me he changed to the 3 piece because Bicycle-Engines.Com asked him to and why they asked him to has never been explained. The only real solution to the 3 piece crank problem is for as many members as possible to lobby Bicycle-Engines.Com and ask them to ask Don Grube to change back to the old 1 piece crank as the standard crank sold with 4-stroke kits. I feel this is a better solution than the convertion kit as once you see one of these new 3-piece cranks you know they are weak, did I mention weak.Įxcuse the dirt and grease she has apx. My feet don't hit the engine and I don't feel so bull legged. The pipe can be pushed over to clear but I felt it would put too much strain on the manifold bolts and opted for cutting and old pipe which I may weld to correct the clearance, leave cause it sounds cool or reinstall the exhaust that comes on the engine. The only problem I encountered was the crank hitting the exhaust pipe. This crank has the same arm lenth as the new 3-piece crank 6". I pulled a crank out of a 20" next bike and put into my schwinn point beach. The majority of bike frames that fit these kits are cruiser type with 1-piece cranks. First I would like to thank the member who called me with this.Īnyone who has bought the new Grubee 4-stroke knows about the problem with the new 3-piece cranks they are for european bottom brackets and the convertion kit cost $29.00 at sick bikes and $35.00 at bicycle-engines.
