Now that is what I call very efficient recycling and true genius with very limited resources. Great job and keep us up to date on how the bike works. (maintenance, breakdowns ......)
Many spoke to me about the limited resource 8 speed hub Shimano. Shimano declares a resource of 50000 km (31000 miles) - I think the raised loading from the motor will lower a resource not so strongly (can be in 3-5 times) and 8 speed hub will serve 10000-15000 km (6000-10000 miles). Such resource will suit me - at us such barrel costs 200$.
Other spare parts work with normal loading (a reducer, clutch).
I already have an experience of use of a similar motor-bicycle. Last year I have made a motor-bicycle with 3 speed hub Shimano and engine Honda GX35 - http://www.motoredbikes.com/showthread.php?t=23339.
The general run has made 2300 km (1500 miles). 3 speed hub Shimano has perfectly fulfilled without breakages. The chain was extended time in 1000 km (620 miles) and it was necessary to change it (it not a problem - the chain costs 5$).
Then I have changed 3 speed hub on 8 speed hub Shimano (at it the big resource). And this year has put all on other bicycle and has established more powerful engine.
