Gallop SR1

Yeah it took me like 3 months before I got my first dual motor 52 volt. Had a highboy s2 max a highboy max pro the finally got my Ausom SR1.

I went from a max pro to an Ausom SR1. Night and day difference, 52 volt 20.8 amp hour battery 41 mph top speed front and rear disc brakes with fast charging. Cost about $1100 with second charger. Also has way way better suspension than any highboy. Forgot to mention 10×3 inch inner tube tires. Edit for additional info.

No doubt, I have no regrets buying Ausom. I have nearly 1000 miles in 3 months as its my daily in nice weather.

I have the bigger version Ausom SR1. Its a 52 volt with basically same motors. I got like 750 miles on it so far and it rips, I would definitely recommend Ausom products.

Kukirin G3 Pro/Ausom Gallop. I weigh 150lbs and routinely hit 40mph on a full charge. I've done upwards of 25 miles between charges limiting to speed 1(14-12)mph. I won't let it drop below 48V. I always leave it in dual motor mode.

Ausom gallop love being able to take my battery out and switch with another

You are *kinda* wrong about Ausom (tho not the one he is listing). The Ausom Gallop also known as Kukirin G3 Pro is a white label product designed by Titan Group which I have been looking DEEPLY into because I have similar needs to OP as a delivery person. That scooter has a 52v 23Ah battery thats removable and the scooter is reasonably priced at €1299 euros for both Kukirin and Ausom tho ausom doesnt sell that model anymore (which makes me extremely confused). Realistically at 25-28mph (40-45kph) that scooter could reach unbelievably stupid ranges and since its a removable battery you could buy one that you leave at work over night (if possible) and double that range.

If you don't need the portable battery then I'd look into other options like the teverun blade mini ultra with their bigger battery and updated features. That being said, afaik the g3 pro hasn't been meaningfully updated since 2023 so I'm sure newer offerings could be better. Otherwise, the g3 pro is a tank, but imo lacking in range. For reference I've got 2.9k miles on my ausom gallop(near identical scooter). Its 1206wh battery will do 20mi but past that you'll really feel the voltage sag for the remaining ride. I wear size 10.5/11US depending on shoe and I find the deck to be good enough, though I do put my back foot heel on the rear plate. I'd say its been decently reliable, my biggest issues have been with the tubes. It's been documented alot I'm sure you could find posts about it, but basically the tubed tires require very frequent psi checks to prevent flats.
