Bought 2 bikes direct from china as they did not have stock in Australia. I wanted to test the bikes for doing excursions into a nearby national Park with steep hilly trails. The bike can not make it up steep hills. On the way down from the first ride into the hills the front brake failed, leaking hydraulic fluid. I was told by Emilee from the factory in China that they would send a replacement brake set. It has been 3 months and all my requests for help are ignored. This company is not at all responsive to emails and seems the warranty is worthless as they just ignore you. Absolutely no point buying this product if there is zero after sales support and no warranty. Very disappointed, feel like i have been ripped off
