I wonder if these large wheels will do away with trolley handles. how many use them instead of pushing the top of the wheel? I have an Abrams, and I prefer to use the trolley handle. However, because the trolley handle is so flimsy, I sometimes just grab the rear handle and use that to push the wheel around while I am walking it. My preference is for the manufacturers to make sturdier trolley handles. 1 Quote Link to comment Share on other sites More sharing options...

I am of the opinion that they all use the identical motor including Lynx(3200W). I am a little disappointed. If it's slightly faster than my Sherman S then that's fine with me, I'm more interested in the extra battery capacity as I like to go for very long rides. I'll be interested in seeing the impressions from reviewers once they get demo units. 4 1 Quote Link to comment Share on other sites More sharing options...

The original Abrams was already inferior to the Sherman in every aspect, the only thing it had was its bigger wheel. And now, with the trend moving towards 16'' and 20'' wheels I dont know what such wheel would really be good for. 24'' wheels are so huge that the niche is only big enough for the Master Pro, if that. A lightweight, 24'' or 26'' wheel driven by a small, geared, high-rpm electric motor like what the e-skate people use would be pretty cool though.

meepmeepmayer Posted July 6 Share Posted July 6 It's going to cost more than the Lynx or the Sherman-S. And with how popular the few LeaperKim models are, I'm not expecting any price decreases for the existing wheels. So... 4700? 4999? Quote Link to comment Share on other sites More sharing options...

How is that supposed to suffice for 100km/h? Max speed doesn’t have to do with the motor power. It is the higher voltage that unlocks higher speeds. Somewhat simplified explanation, the higher speed creates higher back EMF voltage, once that voltage equates your powertrain one the wheel can no longer accelerate and you dive. The more voltage you have the faster the motor can spin before generating that same voltage. Field weakening reduces the back EMF and helps unlock a higher speed than the motor is rated for. The motor metric that affects its rated top speed is the motor KV, but not the wattage. You have VESC onewheels with 750w motors doing 42mph. Higher top speed is the main reason for this higher voltage wheels, yes wires can be thinner too, but that’s not the main reason. 6 Quote Link to comment Share on other sites More sharing options...

It's going to cost a lot no matter where you get it (outside of China), which was the case with my S. But given how great my Sherman S has been for 2 years, 3 months, and 19,694km's into ownership I'm hoping the L will be just as great, despite the cost.

It sounded like you don't feel like you are looking for more stability with your 16" Patton. Jimjam may have a different opinion, but I have zero stability issues on the Patton unless it is gusty windy conditions. Low 40's mph frequently and it just goes. Peopke that aren't used to smaler diameter tires may find it unstable in comparison...but I call it lively and nimble. 3 Quote Link to comment Share on other sites More sharing options...

I ride a V12 with tire pumped at max pressure and for a long period I was riding with the leg pads quite loose and had frequent wobbles at high speeds when hitting bumps in the road or braking. As soon as I tightened the pads around the legs most wobbles disappeared. Of course you have to learn how to avoid creating wobbles yourself when braking or changing direction and how to let them clear away if they appear, but this simple move matters a lot.

It sounded like you don't feel like you are looking for more stability with your 16" Patton. Way more stable than my v12. I am honestly not looking for much more than the Patton offers. But would love the smart BMS, and other enhancements. I am quite paranoid about battery fires, etc. all tho LK has a great record even on older non smart BMS wheels. Also, I am really a small person and light, so the thought of a bigger wheel while not something I am against, is not really a need for me. Plus the suspension on the Patton for me is quite perfect. But I do understand why people need better. 1 Quote Link to comment Share on other sites More sharing options...

My opinion is pretty much in line with yours. I have very little stability issues. I also ride with no pads. The only one point to note is I have a pedal lowering kit. Which made a slight difference, but mostly in mounting and unmounting. Which as a short guy was always a bit of sour point for me lol. I sometimes stumble and it's probably funny to watch. 1 Quote Link to comment Share on other sites More sharing options...

I sometimes stumble and it's probably funny to watch. I put a pedal lowering kit on mine too. Interestingly, I feel like it made the Patton more lively and responsiv when accelerating. It did not seem to make things any more stable at top speed. But enough about Patton...this is a Sherman L thread. 2 Quote Link to comment Share on other sites More sharing options...

It absolutely does have to do with motor power, at least as long was we are talking about an ordinary shaped wheel with an 80kg adult riding it. 3.200W is just not enough for 100km/h, certainly not if you're standing on the wheel and almost certainly not when sitting down either. It doesnt matter how much you fiddle around with the voltage and back EMF and field weakening or whatever, at the end of the day it is raw power that is needed to overcome the air and rolling resistance. It would easily be enough with the rider planking on top of the wheel and everything encased in an aerodynamic teardrop shape, but not with wheels as we know them.

Is like saying a sports car speed doesn’t have anything to do with its motor power. Of course it has. What he is actually trying to say is that voltage plays a limiting role in a non-geared, direct transmission permanent motor. Quote Link to comment Share on other sites More sharing options...

I wonder if these large wheels will do away with trolley handles. how many use them instead of pushing the top of the wheel? No, don’t think they can or should get rid of the handle. I go shopping with my Sherman S and I use the trolley handle a lot. I push it through my helmet when I’m going shopping so I don’t have to carry the helmet around or put it in my bag. If they got rid of it, I would not buy it. The sherman s (and this one) type of scorpion handle takes no additional space whatsoever so you can just slap it on there. No reason not to. 4 Quote Link to comment Share on other sites More sharing options...
BKW Posted July 7 Share Posted July 7 (edited) I just briefly went over the specs, this is almost ideal to what I'd want in a wheel. A long-range, powerful, suspension, WITH STRONG TROLLEY HANDLE LIKE THE CP (EDIT: plastic handle it looks like [cries inside]), light weight for its specs, 20 inch wheel. I don't know enough about the safety stuff so I won't comment on that.. if this wheel had a strong waterproof rating this would be my ideal wheel. As it stands, considering I do food delivery, this would be on the top of my list for my next pick, especially since it's coming from leaperkim and their reliability/durability. The V13 has always been something I've been interested in due to its waterproof rating and package.. I'm assuming the pedals are much improved from the Sherman-S? Also, the ergonomics look good too, and I'm sure it's pretty rugged to boot, which is always a consideration of mine since the parts are always freakin' expensive Edited July 7 by BKW 1 Quote Link to comment Share on other sites More sharing options...
Popular Post Jason McNeil Posted July 7 Popular Post Share Posted July 7 (edited) Finally have permission to share... In comparing to the Lynx & GT PRO+ what's quite remarkable is that they've managed keep the SL on strict diet, where the incremental weight difference between the Lynx is almost entirely attributable the additional 1,300Wh of battery cells. Total footprint is only 0.2" wider, while the GT PRO is 2.4" fatter & nearly 10kg heavier! Released specs have the 130kph freespin vs 125kph on the Lynx—maybe a FW update coming there too?. One of the new innovations featured here is 'total' hall fault-tolerance, e.g. if for some reason, there's a hall sensor, wire, or localized controller fault, the Wheel will not only not cut-out, while riding, but has the ability to operate from a dead-start & come to a complete stop without loosing balance, this is apparently a first for any Wheel—it's possible this will be rolled out on other LK models later.

I wonder if these large wheels will do away with trolley handles. how many use them instead of pushing the top of the wheel? They absolutely need trolley handles. Pushing the top of the wheel just makes things cumbersome. Really, they all need to copy how the CP did it with their CNC handles, which blew away all the crappy easily breakable trolley handles like the Sherman Max (I've broke trolley handle probably 6-7 times and it's not cheap buying that thing all the time). Trolley handles are essential. Take note from the CP's design. The CP's CNC trolley felt indestructible. I'd happily pay extra to buy a trolley handle once and it not break than buy a cheap trolley handle that always breaks and then shelling out more money in the long run. Yeah, I got a little bit of a pet peeve with crap trolley handles... The only issue with the CP trolley handle was the base which was indented in the wheel which would be an area where water would collect. Fix that part and it'd be perfect Edited July 7 by BKW 5 Quote Link to comment Share on other sites More sharing options...

It's not possible: the Lynx @ 88lb/40kg is as light as a Wheel can be with those specs (with current tech), the Sherman-L is just 6.5kg more. The additional 72x cells x ~72g/cell = is 5.184kg, this exclude additional packaging, BMS surface area, casing, etc. By way of perspective, the EB GT PRO+ weighs 10kg more than the Sherman-L! 4 3 Quote Link to comment Share on other sites More sharing options...

I mean, even though the magnesium chassis is already very light, and it's amazing what LeaperKim achieved with the Lynx and the Sherman L - magnesium's density is still 1.7 g/cm3. Plastics, like CF-nylon, can be around 1.2 g/cm3. But I guess with large wheels the metal casing just makes more sense, I was just theorizing of what would be possible in the future / on different, possibly smaller and cheaper offerings from Veteran 3 Quote Link to comment Share on other sites More sharing options...
