I use 2x 6374 turningy 149kv motors on my trampa build. I’m in love with the torque it provides and the hill climbing abillity. However my top speed is at 38 kph with a gear ratio of 6:1.
I want to be able to reach around 60 kph just for the heck of it (i need to lower gear ratio and get other motors). How much offroad capabillity would i have to sacrifice if i switch to 190kv motors instead? I see alot of people running 190kv motors on their trampa boards. I’m not sure if they use their board primarily in urban areas.
Basicly, i want higher top speed but i still want to be able to shred mountainbike tracks in the forest, would 6374 4400w 190kv motors and a gear ratio of 4:1 work fine in heavy offroad conditions and for hill climbing?
Ohh really? Is it too weak for offroad or does the urban driving also become limited? I feel that a trampa board should be able to handle higher speeds than a normal longboard setup? It feels more stable.
I have the torqueboards motor mount and pulley kit, it is 72t 12t. It was the only option that TB offered. Ive already ordered 66t and 15t sets from trampa, this will get me to 47 kph. I also ordered 18t motor pulleys but im not sure if that one will work since the diameter might be to large.
6374 motors seems to be more than enough though. I know my gear ratio is high and i use 150 kv motors but from a standstill on steep hills i easily reach top speed in like 5 seconds. That’s why im curious if a 190kv setup would work almost as good on hills and off-road. Right now i feel like the board could climb a wall, it has way more torque than necessary
Cool man, thanks for the info! as you have experience of a trampa going at 32 mph (roughly 52 kph) would you say that the board handles the speed well? Do you consider higher top speed to be dangerous?
Nice to see some math! Hmm well that much loss in torque is not worth it i guess. How about using 190kv motors? My current motors are 149 kv 3500 watts (80a max). Would motors rated with 192 kv 4400 watts (100a) max automaticly mean less torque? Since they are rated for more watts that should eliminate some differences?
50km/h is the mark for me when it gets more hard to don’t fall into speed wobbles.
If you have a confident stand and the right dampas 55-60 shouldn’t be an issue on good roads.
Which ply deck you have and how heavy you are?
