Re: Which way to go
Bikeberry likes to ignore you once they have the order, and often get even simple orders wrong.
I bought one kit from bikeberry.
Never again, regardless of price.
I use mingsinternational or rose 326. (same vendor)
More than 20 kits and counting with only one bad coil (which was replaced free and fast)
If more is better, then too much is just enough.
If you can't afford it, build it yourself.
