The EV4 Gremlin is a portable electric three-wheeled scooter made by a Polish company.
This product has two front wheels of 10 inches and one rear wheel of 16 inches with a 350W brushless hub motor. The movement is fun and it has a flashy fluorescent yellow-green color, giving off a gremlin-like feel as the product name suggests.
There are two types of EV4 Gremlin: a self-assembly kit and a finished product. The prefab type can be assembled like a plastic model without welding or gluing. However, the battery is missing in the assembled type. The finished product can be continuously driven up to 30km at a speed of 25km/h by stacking three 12V batteries using gel electrolyte. It weighs 37 kg with batteries and 27 kg with lithium-ion batteries with a range of 40 km. The price is 1,000 dollars. Related information can be found here.
