I have to say I've been pleasantly surprised acceleration wise with my Shengyi hub motor (STD wind/8T). It's certainly not neck snapping, it's only rated at 500w but with a full twist of the throttle I'm putting 1000+ watts through it (BaseRunner controller and 52v battery) and with a little...
😄 ... another example of the multitude of benefits of having a throttle.
It will be interesting to hear how you like the inserts. I'm not sure what to think as I've heard so many very pro and very con experiences.
That's "probably" true, but it's so hard to get good verifiable specifications on items like the BMS that we're left with more anecdotal experiences and the manufacturers overall ratings which are usually very conservative for monetary and legal reasons.
But it depends on what you define as "typical". I have a 52v 14.5 amp/hr battery from Grin that like some others in their portfolio can be charged at up to 8 amps.
or XLR, or "mini XLR", or ST3, or ... ;)
Plus I believe that another characteristic of the battery (aside from the robustness of the charger connector) that needs to be considered when thinking about faster charging rates is the particular BMS used.
Uh, you all do know that "Hawaiian" pizza is Canadian invention, right?

But since we're all in this together I'll let it slide, just this once ... ;)
With all the posturing that Belarusian forces are doing along the north western Ukrainian border (and my gut tells me that they're really just posturing and have no real desire to go anywhere) I'd like to see Poland quietly place another one of their highly mobile heavy armor divisions that...
Agreed, but the Grin numbers appear to be well proven (both from bench testing and customer experiences) and apply to the common materials (gears, adhesives, etc.) used in popular hub motors ... and so seem to be very reasonable guidelines to follow regardless of the source of the motor.

Thanks Randall, It was enlightening. The survey contains some really interesting examples of a wide variety of cycling infrastructure. That dashed green diagonal path across the big intersection was truly eye opening. A few characteristics that weren't obviously present (but could generally...
With those requirements (which are very similar to mine), and a suitable budget (which I don't have) that would be my choice. In my case I'd also keep my lighter weight road ebike to go with it but for all the other jobs it looks almost perfect. Personally I'd also chafe under the Bosch system...
That is exactly the situation with just about any large displacement engine and automatic transmission combination. There are indeed a number of known weak points in the drive trains, but what prevents them from failing is built in "slippage" when too much torque is applied on start up. It also...
I've got to ask ... over the past 20 years have you never unpacked a new electronic device or appliance?
"THAT" is clearly the tab to make it easier to remove the temporary protective film on the display.
Ravi,
That's a really interesting position and plan. I'm assuming you're building 14s battery packs but advertising and managing the packs as 13s (48v). Aside from those folks who buy soley/mostly on specs I don't see a real downside for bikes with mid drive configurations where top speeds can...
That's what I use them for. 9 spd Shimano 105 road levers with V brakes (I think they're Nashbars) on my road/gravel ebike. It's not like these levers don't work at all, it's just that the braking force seems better with the TAs in place.
So instead of settings with voltages and/or percentages of a voltage and amperages it would be switches for specific functional settings? I think that would work for a lot of folks. I hope a display for voltage and amperage monitoring is something that can be kept in the design.
Define "booster". I ask because I've read different descriptions of brake boosters.
The TAs don't change the total amount of cable pulled by the lever, it just becomes non linear. With the TA's cam setup the first part of the lever travel pulls a different amount of cable than the latter part...
They increase the amount of cable pulled by a little bit when the brake lever is initially pulled. So less pull on the lever creates a bit more leverage at the brake itself.
