YUME - Y10

Mukuta 10+ is pretty up there, the gold standard for 40mph scoots is the Nami Kilma, though. The Vsett 10+ can be looked at.

Honestly for your weight plus hills and the price range you provided it's almost impossible to find something that will suit your needs to be honest. You're going to have to be willing to spend a little bit more. https://www.yumescooter.com/collections/commuter-off-road-electric-scooter-for-adult/products/y10-electric-scooter-40mph-2400w This is the closest thing that suits your needs and isn't too out of budget. Anything else were talking $1500+ range 😬

The ausom is the way i would go if you really like the design. I'd highly recommend at searching yume scooters. I have a y11+. Customer service and support has been good. The y11+ is a monster and I really don't recommend it if you ever EVER have to carry it up stairs. The y10 i will recommend for you. You're going to want dual motor to do stuff off-road. You don't want to be too low on power that you have to walk/lug the scooter up wherever. Their swift model advertise 20° hill capable. Their y10 has higher weight capacity and dual motor and robust suspension. For some reason yume scooters didn't quote a hill climbing angle capabilities for y10 model. My y11 is 30° hill. Swift is single motor 20° hill. So somewhere between there. You may not want the top speed. I have powerful scooters but I don't like going fast. But to have power available when you need it it is what you want.

I have a yume scooter. I have the y11+, the x11 is similar in specs and same with Hawk pro wide scooter. Those scooters are dual motor and will practically climb a vertical wall. The normal Hawk model and the y10 are a lot more modest.... but most definitely not weak by any means. The hill grade climb capabilities is not rated as percentage, it's rated by degrees which is MUCH more significant than %of same number. Hawk is 60v so you get more power and range... but the y10 is very similar just less voltage and a little less power and range. Between all those scooters, your main decisions will be more visual esthetics and what performance the geometry suspension provides. I have only ever used "fork type" front suspension and never c-type so I don't know the difference in performance on it personally.

Yume is credible. Their customer service is functional just need patience. Also, their claims are not falsified. I was surprised when my Y10 hit 40mph
