    E-bike specific Internal Gear Hub by Shimano for 2019

    Read my comments. If you are a casual rider and never ride in freezing temps then maybe it could work for you. Just remember it really is a 3-speed. But if you are an avid cyclist, like smooth low drag bicycles and are going to ride also in the freezing temps then this hub is garbage for that.

    BMC Alpenchallenge AMP E-bikes

    I think the sizing is weird too for this frame. I am 175cm (5’9”) and have a small frame. My inseam is shorter than usual at 77cm. I also consider 580mm TT lenght (583 on medium) to be maximum for flat bars and drop bars need to be 535+mm. I had hopes I could ride this small with drops but no. I...

    I am aware of it. Though it is hard to find and requires longer belt. So it will be quite expensive change. I used teflon based oil meant for rollerblade bearings to the hubs shifting mechanism. The sticking has gone away and has not returned yet. I treat the hub as a three speed and as such...

    E-bike specific Internal Gear Hub by Shimano for 2019

    I'd like to add my view of the 5-speed hub. I have had it just a little while and rode with the bike just above 200km so this is no long term review. I just bought an ebike. It's the BMC Alppenchallenge AMP city with 5-speed shimano igh and belt drive. First thing to note is that with belt you...
