Really well designed bike. Well made. I particularly like the fact that the lights are controlled from the handlebars and powered by the battery - it makes so much sense. Otherwise the bike is quite a lot lighter than many e-bikes on the market. It's also well balanced on the stand - too many bikes fall over far too easily when propped. I have only had it a few days, but have tried progressively longer trips to see what the range is like - so far, so good - and I would say the minimum distance the battery can help you will be around 30-35 miles. Putting in more significantly increases this. Well done Mark2 - this is a product of which you should be proud.
