The best budget scooter you can get your hands on.
Its overall a great scooter. I dont think any other scooter will give you this much features with comfortability like this. Affordable as well as looks much better then more expensive ones. Definitely worth every single penny it cost. Best mileage and best looking scooter. You definitely dont wanna miss this out. Just got a chance to review it and i would like to get this one soon one day. Driving it seems like smooth as a feather. Features wise it is packed and loaded with latest features what most a basic consumer need and expect from ab electric scooter. Not all like overhyped ones but the ones that people would definitely use. And looks wise it looks crazy looking good with amazing dead edge sharp looking scooter. Amazing color and great design by the company. Hats off to every single one.

Economical Sturdy Electric Scooter
I purchased it for my daughter who travels 50 to 60 km daily. I researched available popular models in the market like Bajaj Chetak, Ola s1 pro, TVS I Qube, and B gauss and its design is similar to Bajaj Chetak electric. It has three modes of drive economy, sports, and normal drive along with reverse mode. It has three colors. It has a good pick up which is good for city driving. Its problem is the display board is not visible in daylight. The price could have been competitive and less than one lakh rupees.
