This is in New condition, having had very little use. Shimano two speed auto, very easy to ride as it changes up and down for you. 36v 10.4ah Samsung celled battery. Motor is the well respected Bafang 8fun unit, as used in most Woosh, and many other electric bikes. Its known for its good performance, frugality and reliability. Also has built in lights, lightweight mudguards, bell, stand, and a rack, which has a 25kg carrying capacity, this shows the strength of the frame, 25Kg is a lot of weight! The battery is in perfect condition, comes with two keys, charger and manual. Very well made, well designed bike. Lightweight at 20kg with battery on board. Walk assist, 3 power settings. Originally cost £1299. Less than two years old, current model. There is a very good review on this forum, and lots more on the internet. It seems Momentum are owned by Giant, and built in their factories. Bargain at £495.
