More torque with new motors??

First off Id like to say I'm new to the evolve community. Ive had my GTX for a few weeks now and like always I get the itch to modify its performance in some manner sooner or later. I'm at the limit of the boards max weight (225lbs) and have found that ECO mode, the mode that gives the best range doesnt have a lot of torque to get up even the smallest of hills, I dont know if this is because of my weight or something else. So I looked into getting a different gear change, while yes I get more torque I sacrifice acceleration/speed, so that was a definite NO in my book. Then I looked into the Racestar 140, 190, 200Kv motors. While Ive seen nothing but positive reviews I can never get my question answered, do any of them, with gearing staying the same..offer any more torque? The difference in torque between FAST and ECO is substantial in my opinion, I'm trying to find a better balance between the two so I dont have to switch into fast mode just to get up a hill and waste more juice when I'm riding on long trips. A bump in speed, torque and range would be amazing. I just did a 17mile trip back and forth and was able to make it with one stop for food and a quick charge, want to see if I can expand on those attributes of the board without sacrificing too for one or the other.

 

RjodEvolve3297,

Do you ride the AT setup or say 97mms? You will get less distance on the ATs. A new board with 83, 97 or 107mm wheel should give you close to a 19 to 20 mile range on a full charge without issue. The ATs will get you much less than those, 15 miles give or take a mile or two. Yes weight, the number of hills, the hill inclines and how hard you ride the board all matter but….. I would suggest before tweaking the board by replacing parts you work on controlling the board in the Fast and GT modes. You would think ECO will give you the best mileage but I haven’t found that to be the case. I pretty much ride in GT mode all the time with the R2 remote. The acceleration curve with the R2 is much easier to control. When the battery starts to get to the lower end it will switch you to ECO mode automatically especially on hills. The evolve battery isn’t the best battery to begin with but for the first few hundred charge cycles it should be more than enough to stratify most riders. Now if you really want to change things you can go with different wheel hubs and the number of teeth will either increase speed or torque and there are 3rd party motor gear parts you can replace as well but if you haven’t mastered the board in Fast or GT modes yet IMHO you would be spending money when you don’t need to. Hope this helps and Ride On!

P.S. I know they advertise close to a 30 mile range but even new I think the best I ever achieved was close to 26 miles

 

Thank you for the response! Street GTX setup with the 97mm wheels. Evolve tested their range with I believe 176lb rider on eco steady at 12mph. I was easily able to get 30+ by regularly staying in Eco..the ride was 17.4 miles one way, it only died about 1/4 mile away from my house and STILL had power to move itself just not me. On hills, I jumped to FAST Mode to climb hills. What Im trying to solve is whether or not without any gearing change can I get a bump in speed, acceleration, torque, and range with racestars 140, 190, or 200 Kv motors.

GT mode is awesome, but its giving max to the motors, sure for a decent scoot somewhere its great, but for long distances like the one I rode yesterday 17.4 miles there and back home, it isnt practical.

FAST mode is definitely more efficient, I regularly run in FAST mode work as its only about 5ish miles away.. however, it does send more power, and therefore Ive experienced less range being in that mode full time, I'm not slamming the throttle and allowing the board to coast when it can.

ECO is great for range, especially if your careful with the acceleration, however, the torque drops SIGNIFICANTLY. That's the issue I'm trying to solve.

I dont what to change gears on my board as I lose top end speed. What I'm thinking is if I bump up to the 190kv, more power will be put to the road, GT mode will be even more insane, FAST will be faster, and ECO would have a little better torque curve to get up said hills and not expend more battery just to get up a hill thats not crazy in gradient.

I'm trying to find much more balance between ECO and FAST in terms of torque and getting up hills.

 

High kv motors will have less torque but spin faster at top speed they will be far worse up hills

 

I get that part, however with the 12T high torque motor gear that board bumpers offer, won't it somewhat lessen the loss of speed?

 

I'm passed the point of no gearing. I understand that without some sort of gearing change I will get no difference in torque. However the combination of a more powerful motor and the 12 T motor gear, dont you think I can get a bump up of both torque, acceleration, and speed?

 

Hi there, I’ve had the board bumpers 12at gear put onto both my boards (Carbon GT). I think I’ve lost about 7 - 8kms from the top speed which I’m happy with. I weigh 105kgs and I wanted a little more torque than speed. I’m now easily getting up pretty much any hill I try. I also have the One limited board, I’ve fitted it with the 38tooth gear that Evolve offer. That change has also taken a little from the top speed somewhere between 5-10kms but it’s given the extra torque I was looking for.

All of my boards are now geared for torque, trading some speed for power was a no brainer.
I’m surprised Evolve don’t offer the more torque option for larger riders.

 

That's what I said. Do you feel a difference in torque going up hills in ECO mode too?

 

I’m not sure uphills and Eco Mode should be seen in the same sentence.
The 12t upgrade has added significantly to the torque on my boards but I couldn’t comment on Eco as the only time I use it is when battery lag automatically kicks me back there.
You would have no problems uphill in fast and GT will cover almost anything you’d want to try.
I’m not sure you’d need any mods before the short warranty expires.
After 6 months you’ll probably never use Eco either.

 

You should try it and get back to me.

You see heres my thoughts behind it. Although voltage and torque curve is diminished in ECO, youre still adding a constant mechanical factor that doesn't change (12T from 15T motor gear) and that 30% torque should still be applied to ECO mode, so in my mind, you should see a bump in torque in Eco as well.

Id rather use Eco to maximize range anyways. Even though I understand Fast mode is well Fast I still like to improve upon the modes themselves. Unless I get a focbox, the only way to change the performance is motors, which I have (Racestar 200kv) and gear, which I'm about to do.

 

I think improvements in the battery packs might also help with some changes in performance, depending on where you are there are a bunch of different options available.
I’m in Australia and one of the options I’ve found here is at, https://marsen.com.au/products/battery-packs/

Now I haven’t changed to these yet as my Evolve boards are still going beautifully.
It will be interesting to hear how noticeable any performance improvements are after you’ve got your Racestar 200kv and 12tooth gears.

It would be nice if Evolve had a bunch of plug and play aftermarket options for riders. I’m not sure sticking lights underneath counts much when your looking at performance.
