Greetings. I have completed an E-bike conversion of a Trek 8.6 DS with a Bafang BBS01 with a 52V 11.5 amp SharkPack - both from LunaCycle. Overall I am very happy with the conversion and I am continuously in process with tweaking the build.
However, I continue to be made aware that the conversion process has many side effects. Last week, after I changed the stock hybrid tires to a pair of Schwalbe Energizer Plus, ironically, I had my first flat tire in distant memory on the rear tire. I changed the inner tube only to find the puncture was on the inner diameter, not the outer. I thought that was odd. But today, on my way home I heard a pop, then the rear tire rubbing producing a pulsation in movement. I quickly determined I popped a spoke.
Obviously, moving at higher speeds, hitting object etc, produced stresses on the rim that resulted in the spoke breaking and the rim deforming. The rims on this bike are Bontrager AT 650 (700x38c) which by all accounts are low end rims. I've begun the process of looking for a new rim and I'm amazed at how expensive they can be. I'm wondering if anybody has had a similar experience or if any particular wheel offers a better strength vs weight offset, but without spending more $ than what is really necessary.
Comments are appreciated.
