I'm going to see if I can have both brackets/packs on the same bike, and if I need the extra range just switch the motor cable connection between them. I will have to see what kind of range the new battery gets, but yes it's dependent on a lot of factors like how much weight you have on the bike and the terrain you're using it on. About the size of the battery, I think it's mainly just a different format than the previous model, wider and flatter. It also doesn't have a display taking up space like in the older pack. I imagine the range is probably on par with that one.Hi Franken
Thanks for your quick reply and the link. I see someone else on this thread has had a similar problem with motor cutting out. Looked at your link for the new kit, apparently compatible with the older wheel. So 250 quid to upgrade to the new battery / controller pack. It's a rather small battery, even the larger one and I think it would be too small. When they say 30km I take that to realistically mean about 20. (I see you have been considering ways to extend the range.) I do like the idea of mounting the new battery pack in different places as I think the handlebar mount is not really up to the job on the old model, at least in my case. I have a pretty decent pannier bag on the back so I might look into extending the various wires to the rear and carrying the battery in the rear pannier.
