They have not done OK on this one. My battery failed just one or two months after one year of purchase which in Europe market means within warranty. They replied that their purchase conditions are 1 year warranty which is against European law. They just proposed a 20% discount on a new one. This is NOT ok 100G!
Price performance of the product is great. The kit works really well and does keep your bike almost unchanged other than the slightly bigger "water bottle". In other words, your electrified bike doesn't look like an e-bike which is a good thing against theft. In terms of performance, the assistance is effective but the way it engages is sometimes not as expected. Maximum couple (not documented) could be better for steep slopes.
It all works as expected without mishaps
