    With 125% tariffs, will the e-bike market die?

    Meanwhile, small plane pilots still argue about whether to use nautical miles and knots (which has advantages in navigation planning) or statute miles and mph (which makes explaining things to nonpilots easier). Most of the old measurements are based on powers or fractions of two (half inch...

    Ebike rack

    I wonder why they say "not for RV use"... and one of the pictures on the linked page shows it mounted on a RV...

    Need help on choosing my first e-bike! Want to purchase from website.

    How about traveling 1800 miles for a test ride? My wife wanted a Zugo, but she's very short and wanted to be sure it would fit. The company had just reorganized and the only place we could see one was in Austin, TX, and we live in Connecticut. But I needed to go to Dallas anyway, so we flew...

    Ebike rack

    We got this one to carry my wife's Zugo on our camper: https://www.amazon.com/dp/B0BL6QCSTK?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1 It's worked pretty good so far... but now that I got a bike too, I gotta look for a double rack.

    Hello I am new to ebike and am wondering what is happening when the assist will shut off while pedaling for sometime in inclement weather?

    If it's only (or mostly) happening in wet conditions, probably something is getting wet and shorting out. Next time it happens, look the bike over and look for wet electrical parts. If you find a wet connection, dry it out and see if it starts working again. Then think about how to seal it to...

    Show us pictures of where you ride your ebikes!

    Quick ride after work last night, this is in the woods about a half mile behind the house.

    Larger chainring for Radster Trail?

    The amount of torque that can be transmitted without excessive wear or outright failure. Typically a sprocket manufacturer (at least in the industrial world) will publish tables of the allowable power their sprockets can handle at various rpm. A larger sprocket can handle more power than a...

    Larger chainring for Radster Trail?

    Wow, that's pretty extreme. But yes, when designing chain or belt drives there is a correction factor for the amount of wrap around the smaller sprocket or pulley. It takes into account the strength of the teeth and also the reduced radial force holding the chain or belt into the grooves...

    Larger chainring for Radster Trail?

    It's not about how much of a workout I get, it's about how fast I have to pedal to maintain higher speeds even in the top gear. I find myself varying the PAS from 0 to 3, usually 1-2, depending on the slope. All the class settings do is control the speed where the motor cuts out, and disables...

    Larger chainring for Radster Trail?

    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.

    Larger chainring for Radster Trail?

    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...

    Larger chainring for Radster Trail?

    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...

    Phone won't charge from bike

    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...

    Phone won't charge from bike

    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.

    Phone won't charge from bike

    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.

    Phone won't charge from 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...

    Larger chainring for Radster Trail?

    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 Radster Trail owner

    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...
