    Charger question - feedback

    I wouldn't expect this at the $100-150 price point, but as an option for a luxury charger the ability to leave it plugged in full-time and manage/monitor the battery live would be useful for some. For daily commuters, there could be huge value if the charger could be programmed to wait until...

    Charger question - feedback

    I bought the Luna charger you pictured (Grin Satiator was backordered when I tried to order one), and like it a lot. 1.5 yrs use with many dozens of cycles and no issues, although I have read that reliability can vary. It has the right basic features for me in that it has the 80/90/100%...

    eBikes overtake Road Bikes

    "Cheap" bikes, electric or acoustic, will always be the largest market share in the space. No one up here buys a bike from Canadian Tire or Walmart (CCM, Supercycle, low-end Schwinn, etc.) and expects them to last 20 years. If they do, great, but most are expected to last 5-10 years at...

    eBikes overtake Road Bikes

    Here in a west-coast bicycle friendly city, I would definitely suggest that the e-bicycle sales market is about to, or even has surpassed the traditional bikes if you consider miles ridden. There are at least as many exclusive e-bike stores as exclusively traditional now in my city, and most...

    eBikes overtake Road Bikes

    I believe we will look back at the introduction of e-bikes to the mainstream as we did the introduction of the modern 10-speed drivetrain in the 70's. We are still a few years off of real standardization and uniformity of product, but I'd argue that this will eventually be seen as just the...

    Electric bike cost

    It's been discussed for sure. https://electricbikereview.com/forums/threads/the-true-costs-of-owning-and-using-an-electric-bike.22739/ and somebody over on endless-sphere made a neat spreadsheet calculator for anyone to use...

    Bafang Ultra "Smooth" tune by Mike at Frey

    I'm certainly not a programmer, but as I understand it the move to Can bus makes total sense and should be a benefit down the road as more third-party manufacturers build with Bafang components and integrate other smart parts. Can bus needs no central controller (Host) as each Canbus device on...

    Purpose of fuze?

    And just as an aside, there was a random comment made on a Nakto Youtube video on the battery that said their own battery had a second fuze on the internal wiring harness, and the stock fuse wasn't connected in that specific case. Across many manufacturers, odd construction variances and...

    Purpose of fuze?

    Did it have power at all from day one? Or was it completely unresponsive since arrival? Sounds like BMS may be the culprit, but I'd keep pestering Natko as you have warranty. As an aside, if the battery voltage drops below a certain threshold, the battery sometimes won't wake-up and accept a...

    Purpose of fuze?

    That's the circuit board that controls the battery and charging circuit. (Battery Management System). If that goes, or sometimes there is a soldered-on fuse, you need to swap that board out. As Uma said, check the charger as they are one of the most common points of failure. And if you can...

    Push Bike Backwards from shed, chain falls off

    I'd think standard 'fixie' chain tension would be appropriate, which would be roughly 1/4" to 1/2" deflection in the top chain either way from static, or 1/2" to 1" inch total travel (max). Slightly looser is always better than slightly tighter for longevity. But your plan to drop in a...

    Push Bike Backwards from shed, chain falls off

    Where is it popping off? Right at the guide wheel? Or the rear cog into the Rohloff hub? I'd check the chainline first, looking carefully from the rear, make sure the rear cog and the front chainring are very much inline and no visible offset. Then I'd check the tension. if you don't have a...

    Push Bike Backwards from shed, chain falls off

    Right off the bat, that is a flat guide wheel, and that is typically used for a belt, not a chain. Interesting for R&M to use that one, and not a traditional grooved or tapered MTB chain guide wheel like these: You could likely swap one out with the model like the Blackspire at the top, as...

    Using EBR to bully reseller.

    Overall, I actually like the fact that online reputation management is a thing now. In the old days of the yellow pages, there was no easy way to know which businesses had good reputations if you didn't have access to word-of-mouth referrals, or maybe a local BBB telephone line. Neither of...

    Insuranse rejects a claim on the basis that e-bike is a motorized vehicle.

    And furthermore, if you unplug the throttle, the bicycle still functions as designed. You can't do that to a moped or motorcycle. I would definitely challenge that interpretation. And as an aside, those who are quick to try and get their ebikes registered as mopeds or motorcycles because it's...

    Cat whiskers

    I haven't tried the cat whiskers myself yet, but we were discussing them and similar items in a couple of other threads this summer, and most folks said they work well up to reasonable speeds (15-20mph). Beyond that, they still reportedly get overwhelmed by the wind noise. I have found that...

    Bafang Ultra pedal engagement issue

    Yup. the Ultra is just a bit too powerful for conventional drivetrain parts. It can be managed, but you have to be on top of it from day one. I shredded my first drivetrain pretty quickly by being a little to fast and loose with it, but the second is doing far, far, better. A minor...

    Bafang Ultra pedal engagement issue

    Which gen motor is it? UART or Canbus plugs? If it's a UART motor, sounds like a great candidate for one of the improved tunes. My update with the Frey Tune completely eliminated the surging and hammer-down on acceleration. Very smooth now.

    About prescriptions...access, costs, emergency supplies

    As a Canadian, I can tell you this move pissed us off more than a little. To the end that we had to place emergency parliamentary orders to limit exports to the US. We are a tiny market for pharmaceuticals, and we don't produce many here in-country. Most actually come from the US and abroad...
