Really pleased with the F20 Pro, slight problem with the hand grip but quickly rectified from customer services who arranged for a replacement to be sent out. Battery range is getting better with use and would probably get the stated range with moderate pedalling and assist level 1. Build quality is very good for the price point, an addition of a rear carrier bag I purchased of eBay sets me up for a good full day out with a packed lunch, waterproofs, tools and spares. Well recommended. Thank you
