I guess it depends on your budget and personal preference.

For me I don't see how much more value you get from a kit by Bionx retailing for $1890 versus a kit from AmpedBikes retailing for under $500- at the end of the day both will propel your bike pretty much the same way.
It's true that Bionx has some extra bells and whistles but I am not very impressed by them personally.

There's no question that the Valencia is a nice bicycle, but it is very pricey. I think that you can find better values out there for complete solution ebikes.

I work in the business and don't wish to use this forum for shameless self promotion so I will refrain from mentioning brands. If you are curious you can look at my profile or send me a PM.
