Evolve Bamboo Battery
Great product, I've been using it for only two weeks, it gave 30 km in range with the all terrain wheels and 40 km in range with the street wheels (101 mm).
Two in one kit
THE AT tyres that come with 2 in 1 kit, are very good, and surprisingly grippy.
The street wheels 107 F1's are a excellent complement to the AT tyres.
