For anyone looking for an awesome carving board, electric and all terrain capable, i recommend a Carbon AT from Evolve. I bought one of these a month ago (see photos) and they're awesome fun. RRP is pricey but well worth it imo. Charge time 2 hrs for a full charge. Speed to 40 km/hr (2 speeds). Deck built from carbon fibre and kevlar mix.
