Sorry, I literally only just noticed that I had a comment on one of my videos ! It is fantastic for going up steep hills, which is why I bought it. The extra gears on the GB3 model give me the additional range of assistance. My regular cycling routes have some VERY steep hills and I can get up them. Obviously it takes some effort still, and this bike is not as powerful as the Merida with bigger wheels and Bosch motor that I had before, but I am more than happy with the power that 'Little Wheels' has.
