i need help tuning chinese bike

[adam125r4]

hey so i got one of these from china it's very underwhelming to say the least. its a 72v 5000w bike with a 72v 29.7AH battery and 72v 80A controller. i can change the settings and such from my phone via bluetooth but i don't understand a lot of the jargon. it only tops out at 42 mph and the torque from a stop is non existant. i can't even get the front wheel to come up when i mash the gas from a stand still. i heard these bikes come with slow start but idk how to adjust it. also when im up and moving and let off the throttle it still engages the throttle for a solid second or 2 and its driving me nuts. anyone have any experience with these?

I link to the description of the bike and controller would be helpful.

Understand that your bike's preset limitations may be there to keep the bike from self-murdering. Try to understand how well the axle torque retention is executed on your bike before you start asking it to do something stupid.

set your throttle delay to like 300 m/s and set your mid throttle phase current higher to like 140
