G2 Master

You should definitely look at the iScooter iX7 Pro.It is a dual motor beast and the build quality feels much more solid than the G2 Master. The speed limiting is super easy to handle through the P settings or remote depending on the version.It is also a perfect platform for adding hydraulic brakes since the cable routing is very straightforward.I have been using mine for a while and the torque is incredible for climbing steep hills.

I tried both and the g4 feels way more comfortable / stable and bigger, the G2 master feels much more sportive The suspensions are much better on the g4, the G2 master climbs hills a bit better

Kukirins are really good. G2 max, G2 master, and G4 are your go to. Pick the one that's fast enough for you and you'll have lifelong memories. They're basically a namebrand and have good reliability but for cheap prices. Have fun bro and don't get caught, hopefully penalties aren't too big where you live.

Yeah it’s not great but it gets the job done and it can be replaced by a decent shock later

Can't speak to the quality of the Y1, I have a kugoo and very happy with it.

I have a G2 master

Advertised speed is 60kmh, mine tops at 62kmph on flat ground. Uphill I get up to 50kmph depending on gradient but even steep hills I get around 40kmph as it's dual motor and that makes s big difference. Bare in mind this is an e-scooter. You are asking about bikes but you also said you tried them and kugoo had more torque which is what you want. My original point is that these electric motors don't struggle with speed. It's the advertised range that's impossible to hit cos it needs perfect conditions.

Can't speak about the G4, but I have a G2 master and its a freaking tank. Only issue so far was broken fender from transport. Support was fairly quick and I had a new one in less than 2 weeks. I'm also 6'5" and 200 pounds...no issue with stem height or mobility issues

What did you buy in the end chief ? Give us an update.  I bought a G2 master but within 6 weeks there was a controller malfunction. Error 006 .... Been waiting weeks for the replacement part 🫠  Until it bricked I loved it but 6 weeks and less than 500km does not inspire confidence 

Whats the budget Chief ? Do you see it being for fun also. What speed you want...? Ausom L2 is what i use for my daily 5km commute. Couple thousand km on clock now and no issues. Shes been very dependable .... I also have a dual motor kukirin G2 Master, thats more for shits n giggles, ripping through forest etc. Also been very reliable and a lot of fun...

Kukirin G2 Master. Just lock it in safe mode if the pigs show up. Being a large fellow you want dual motor. My G2 Master at 1500 miles all i have done is change brake pads.
