The Moscow Plus is a fantastic eBike. The 27.5 size is perfect for my height (170cm). Easy to put together (I just followed the video on YouTube). Battery seems to last forever! I added on the front light, bike rack and storage bag too (sold separately as spare parts for this model - note that no screws come). I haven't used the bike on the fire trails as yet, just dirt roads, roads and bike paths. So far so good! This is a great entry level mtn eBike, especially for me as I won't be doing 'too too' extreme things in terms of trails. Great price too (EOFY deal).
