Hi!
Just doing an elation type conversion, but i am still waiting for my crank freewheel. The supplier said he is supplying two chain rings, so i assume one for the motor, and one for the chain drive.
My query for others who have this type of system, is it advantageous to have only one front chain ring, or should I try and keep my original triple chain ring setup?
Thanks,
Rob

Just to clarify, I am talking about the performance of the bike. I'm guessing I'll still have a major advantage over a hub drive system. For those that are wondering, the motor is rated at 250 watts, and I'll be running it at 24v.

What are you doing for a freewheeling crank/BB ?? You say you're buying something from a dealer? Is it new or used?
e.g. when I rebuilt my Charger bike, I ended up buying a used Schwinn (a.k.a. Shimano Front Freewheeling System) thingy.

Just wondering where you got your freewheel cranks and how much. Thanks

My experience with a low wattage motor has been that the more gear selection one has the easier it is to keep the motor in it's top power range. If you can, keep all three front rings.
Thanks for the comments!
Not sure how much the BB freewheel was, might have been $80 Aus?. The whole kit cost me about $265 Aus.
The supplier is Island Earth in Aus.
Should have it on Monday, so will know more when I get it and install it!
It is about the last thing I need to do.
Motor is installed and battery pack is all wired up ready to go!
BTW, it is all a custom install, based on the Elation system.
Might post some pics, when i can work out how to do it!

Sorry, I think someone asked about the brand of the freewheeling crank? I think it is a Currie.
