Can I make my Bafang CST 500W48V rear hub motor climb hills better by changing the reduction ratio of the gears inside the hub? I have the impression that it comes standard with a 5:1 reduction ratio but that this could be changed to 6:1 with different gears. I suspect that this would provide...

I actually misread the graphs in the mid-drive-vs-hub-drive article the first time around. I mixed up the torque and the power and thought that the mid-driver was most powerful at the lowest speed. In fact it looks like the power curve is always a parabola but on the mid-drive it can be...

This article on the effective power of hub motors vs mid motors is amazingly awesome: https://www.ebikingnow.com/blog/mid-drive-vs-hub-drive EDIT: Though it seems like the graph for the mid-drive is with a ~1000W motor? I would like to see how a 250W mid-drive compared with a 500W hub...

Here is one more reflection. Sorry to think aloud so much. The hill that we live on is 26% steep (or more) and this is probably beyond the limits of our Speedbike and most other e-bikes too. However, this hill is exceptional because it is a small private road with almost no vehicle traffic. The...

I am thinking about what J.R. said about having to spend some time learning the idiosyncrasies of a new bike and what WilliamT said about the current bike possibly being quite decent. I do believe that we need a front derailleur but *maybe* that is all. It does sound like a mid-drive would have...

Riding up on a traditional bike is doable but really hard.

We have been offered a couple of trade-in opportunities. I would love some feedback! The options are two Allegro e-mountainbikes, either the CrossTour MTB or the Invisible MTB, which are described at (Link Removed - No Longer Exists). What do you reckon? Is either of these likely to handle our...

Great tool! The estimate that it provides is 26% gradient (steep) but only 27m total climb (short.) The road is not perfectly straight or even and so the peak gradient could be more than this. This is the steep hill that leads up to our house. The rest of the region is also steep but not as...

I called the support number now and they actually told me that it was a mistake to buy this bike. "What you bought is a Porsche but what you need is a tractor." They are going to see if they can help us with a trade-in. Fingers crossed! Is there any easy way to measure gradients? I would like...

We bought the bike from a department store (Coop Bau und Hobby) and unfortunately they don't seem to have much specialist knowledge about bikes. I suppose we can contact the makers of the bike and ask who they recommend. I take the point that for hill climbing it is important to get lower...

I am overwhelmed by all these great answers. Thanks so much!!! Let me follow up with some more newbie information if I may :) I have only tested going up hill with PAS=9. I assumed this is "maximum assistance" i.e. the best choice for steep hills. Is that overly simplistic? How do you choose...

Oh no! We bought and e-bike but we are disappointed with our first real test ride. We live on a very steep hill, in a very steep area (Swiss Alps), and the bike doesn't seem to make it up the hill to our house. This is really disappointing! I am trying to work out if there is a technical...
