Well of course, throw enough money at a problem and anything is solvable. Good luck though getting a single spring made for anything like 'reasonable' money. Been there, tried that.

I don't know if there are standard sizes for fork springs, but if there are, the Sher-S spring size is most probably one. Given the travel we are discussing, the Sherman is using nothing like industry standard. I wouldn't be surprised if it isnt entirely proprietry. 11 hours ago, Slartibartfast said: 90mm is (probably) a good thing if you can get the right spring to match. I think it's workable but with such a small amount of travel to play with, getting the right sag will be critical. Hence the need to get spring poundage just right for the rider. Otherwise, as you say, some people will blow through half the travel just standing on it, others may barely make it move. And having adjustable preload isnt going to fill that void even with 2 springs available. I'm sure lots will just ride it whatever though.. 11 hours ago, Slartibartfast said: By the way, does anyone know what is going on with Fastace's asymmetric fork design. It looks like one side does the "springing" while the other side does the "dampening". Is that how it works? I think this is common with MTB forks. You're right, pretty much all MTB forks have split roles for each leg whether coil or air. 1 Quote Link to comment Share on other sites More sharing options...

Do people want to ride 60mph+ all the time? 14 hours ago, techyiam said: 45 mph is only 73 km/h. Sherman-S top speed is 75 km/h. To ride with city traffic, you need to be able to maintain at least 35 mph to 40-ish mph. But there are hills, headwinds, and bumps. In other words, you need Headroom! Exactly. The speed limits in my area are 35-45mph. I have no problem with speed if I'm in an area that's safe to be going 45+ mph, but the whole point is having the headroom available to do it for hours on end despite conditions.

Good luck though getting a single spring made for anything like 'reasonable' money. Been there, tried that. Buy a 1000 and you'll be fine Don't ask a quote from mass producers. One local Mom & Pop shop has quite decent prices for single custom springs, when they have correct diameter wire in stock. To make a spring you only need a lathe, a tube and some spring wire. Some engineering is needed for correct spring specification. Edited October 5, 2022 by Eucner 1 Quote Link to comment Share on other sites More sharing options...
RaidenHUN Posted October 5, 2022 Share Posted October 5, 2022 Not just that but the V13, for lower price is 137V wheel... 37% more then the 100V Sherman-s. Quote Link to comment Share on other sites More sharing options...
meepmeepmayer Posted October 5, 2022 Share Posted October 5, 2022 (edited) The V13 is 126V and the ShermaS 100.8V - V13 has exactly 20 25% more voltage. (30:24 = 5:4) Edited October 6, 2022 by meepmeepmayer math is hard Quote Link to comment Share on other sites More sharing options...

RaidenHUN Posted October 6, 2022 Share Posted October 6, 2022 Still, V13 is cheaper and we expect 20% more performance from it. The use case of these wheels are the same as well. Quote Link to comment Share on other sites More sharing options...
Popular Post meepmeepmayer Posted October 6, 2022 Popular Post Share Posted October 6, 2022 20 inch vs. 22 inch tire is going to be a notable difference. Let's not forget that. I can't see the V13 being as zippy (relatively) as the ShermaS just for this reason. 3 1 Quote Link to comment Share on other sites More sharing options...
MrMonoWheel Posted October 6, 2022 Share Posted October 6, 2022 Currently I have a preorder in with ewheels for the v13, and while id like that to change in favor of the Sherman S, I think the v13 will be the ideal cruiser wheel. The Sherman S no doubt will be better on rough stuff or off-road, but for smooth road/bike path cruising for long distances I'm gonna have to go v13. I wish they had better suspension though 😂 Quote Link to comment Share on other sites More sharing options...

Compared to S18: they're absolutely long range cruisers And beware, 3024wh is the "more honest" math which only Inmotion uses (3.6Vnom/cell). Every other EUC mfg uses 3.7V. And nobody's actually honest, since C*Vnom is the oversimplified and flattering way of calculating energy... but at least it's simple. Sherman-S is 3456wh, using V13 math. So 14% more range. Just.

No need to change your preorder now and lose your place, since there is not enough info and data available yet to make a decisive decision. Plus, the Sherman-S review from EEVEES should be coming out soon. 1 Quote Link to comment Share on other sites More sharing options...

If you want an offroad, quick to respond wheel, Sherman S. If you want a long range cruiser, V13. And then ... OOOO, the V13 MOSFET is burning up! InMotion will be like "ooo, we will fix! here's a new board!" And everyone will be like: OOOO, all road leads to Sherman S.

It all depends on which way you compare them: 😉 Because the question being asked is "how much higher is the V13's voltage compared to the Sherman", the answer in this case is 25%. If you were asking "how much lower is the Sherman's voltage compared to the V13", then the answer would be 20%. 126V is 25.2V more than 100.8V. 25.2V is 25% of 100.8V. So, 25% more than 100.8V is 126V. 100.8V is 25.2V less than 126V. 25.2V is 20% of 126V. So, 126V minus 20% is 100.8V. 1 3 Quote Link to comment Share on other sites More sharing options...

It's 97 pounds for the Sherman-S. 97 lbs. : a Quick to respond wheel: Oxymoron? Think Abrams, think Monster Pro. On the other hand if you want a 70 km/h wheel that is quick to respond, look no further than the V12. 🙂 32 minutes ago, MrEUCMan said: OOOO, the V13 MOSFET is burning up! InMotion will be like "ooo, we will fix! here's a new board!" On paper, regarding mosfets, there is nothing under spec'd here. The V13 has 42 mosfets rated at 200V, whereas the Sherman-S has 24 mosfets rated at 125V. Both are new board designs. There is no reason at this point in time to suspect one is more failure prone than the other. 1 Quote Link to comment Share on other sites More sharing options...

I realize everyone's idea of "long range" will be different. In my use case I'm sure I'll give out before the wheel does. If it can sustain 30 miles of 45+mph riding I'll be happy.
