Indeed very interesting, thanks Willie
A bit irritating the reply of the seller to the question about upgrading a 5.0 Strida:
EVO drive diameter is 95 mm and all other brackets are 60 mm.
Couldnāt find any contact info of āBikeAidā and they also do not ship to Europe.
(Even if they would ship to Europe one had to add ~34 % of the sum for import sales tax and customs duty - plus shipping costsā¦)
