There are precious few electric truggies. Truggy is sadly a dying racing class in nitro, let alone electric. I guess that's why we still don't see many products.

For two different price points, there are at least the Thunder Tiger ST4 G3 (4S RTR electric truggy based on the bulletproof ST-1), and its higher spec brother, the 6S ready MT4 G3, which is dressed up as a monster truck, but is actually a truggy, again based on the ST-1 and including 6S ready electrics.

Apart from those, another fairly economical way of building an electric truggy is to buy the well priced Hot Bodies d8T nitro kit and convert it. The Tekno conversions are very good. All told you'd be looking at about $480 for the kit and conversion, which isn't bad.
