Nah, you gotta understand the engineer/hacker mindset. I just bought a "real" ebike, these days I have too many projects, but his bike looks like something I would have built when I was younger (well, I did, but with a lawnmower engine instead of batteries... it was quite dangerous!). It's not...

Must be one hell of a helmet...

Not quite sure what you mean by "shift the chain right off a too large chainring"? Where does the strain gauge measure the deflection? Is it inside the hub or at the crank? A true torque sensor at the crank would have to be rotating but I see no evidence of sliprings, unless it's just...

CT and upstate NY. Supercubs are cool, but right now my other ride is a Rose Parrakeet.

Can you elaborate on that? I'ma an engineer so I understand gear ratios, torque, and power, etc., I've designed a lot of geared systems, but I know a bit less about the actual practice of bicycle gear design. If, say, I have a 10% larger chainring, then I would be pedaling slower but with...

I don't necessarily want to go faster; I just want a reduced cadence at, say, the bike's current 28 max pedal assist speed. As it is, I've never even used gears 1-4 even going up steep hills (it'd be different without pedal assist, of course) so I think I'll have plenty of low end with a larger...

Interesting... I tried it again just now, with the phone at about 70% charge state... it works fine, and says "charging", not even "charging slowly" as it usually does on low power chargers. Last night when I tried it it was already at around 98% charge so it would have been in "adaptive...

Hmmm, yes... though it seems strange that they'd put a low current charging port on a new bike these days. Either way, the tester linked above looks like a useful thing to have.

I've already verified that the cable is good, tried another good cable. The phone has no trouble charging on a variety of other chargers. Sometimes it says, "charging slowly", but it never fails to charge at all, except from the bike.

My Radster Trail has a USB port for charging a smartphone, but when I plug in my phone (Pixel 7) it initially connects and shows it's charging, the USB indicator on the bike display comes on, but then the phone displays a message warning that it's charging very slowly or not at all, and while...

I've only put around 50 miles on my new Radster Trail so far, but I'm thinking the chainring is a bit too small. It has a 50t chainring paired with an 11/34 rear cluster, and I find I' rarely using anything other than gear 7 or 8 on the road, 6 or occasionally 5 when offroad. When going over...

New here, new to ebikes, though I did buy my wife a Zugo a year ago. The last significant riding I did was the Schwinn Continental I got 50 years ago (and actually still have). She really likes her Zugo but although I found it fun to ride it's really not the bike for me, too small to pedal...
