BTW @PedalUma what are your thoughts on the strength of the 50T cog? I recall when Shimano first began pushing past 34T, there were complaints from the MTB community that they could literally "fold over" the cog with enough pedal torque. This was probably still in the 9-speed days, and since...

I am a dyed in the wool gear hub guy (actually, recently, modify that to gearBOX guy with a Pinion in the mix). But I wasn't at all familiar with the company 3x3, nor their NINE gear hub, until I ran into a bunch of the roadblocks in the way of getting a 142mm compatible Rohloff. This...

BTW been playing around on the Sheldon Brown gear calculator (yes By George that page is still up and running and updated with the 3x3 Nine hub, OMG) and on it there is a link to Mike Sherman's speed calculator. Unfortunately Mike Sherman's speed calculator doesn't yet have a option for...

Hang on a sec there @PedalUma , you're saying you run a 50T pie plate and an amped-up motor? I'm pretty sure I could rappel up the face of the Kaiser Building with that arrangement. At one time I had considered adding a motor to the existing Xtracycle conversion, a bike I love dearly, but fate...

@Jeremy McCreary I think a better answer to your cadence comments is that I tend to pedal my e bikes like I pedal my analog bikes, fast spin, so I'm evaluating these gearing options with that in mind. If I tended to lug my e bike motors and relax my cadence, I didn't know where I'd be with...

None but one of my bikes have cadence sensors, I'm a high-cadence pedaler but this is largely seat of pants. My knees definitely have a preference for high cadence / low gear to tugging a loaded bike up the hill. Actually, here's something else that helps inform my decision: Yuba's...

That's close to the root of my thinking, @Jeremy McCreary , but I can't really know til I know, ya know? And 99% of the time this low gear consideration will be an academic exercise. Being a heavy gear hub user, this is always my predicament: any consideration for low grading always compromises...

This is a gearing question, or hopefully more a discussion, but first there's a lead-in. For my upcoming project: For the past 8 years I've been running a un-electric cargo bike consisting of an Xtracycle Leap cargo conversion and a Rohloff Speedhub. I've used this bike to tow my kids' bikes...

But they don't. The law is simply clarifying that the reflector, which is already required and has been forever, can also be a combination reflector / light. That's it. No Christmas tree. I would also agree that dark tinted windows are dangerous, but "most of the drivers" is an exaggeration...

I made the assumption that the Europeans referenced good data to prohibit flashing rear lights. It aligned with my observations that flashing (strobing) lights at night, particularly obstructions lights on towers, are difficult to track in the periphery and might lead to driver fixation...

This isn't an AI problem. It's a creative individual pretending to be somebody he's not, and while I'm sure the use of AI to polish up his messages probably helped to him to be a more "productive" scammer, he (unnamed flop-house riff-raff) hatched and pulled off this plot on his own accord, and...

There were many more variables. Interest rates were lower, consumer optimism was higher, and there was (still is) a growing consumer interest in electric bikes. Rad wasn't operating in a bubble. They were a legitimate low priced option for consumers who couldn't pay Trek / Felt / Specialized...

I don't know motors very well, but aren't we already in that territory with Bosch and Shimano? I'm aware older Bosch are gear reduced so the crank and chainring turn at different RPMs but I assume are mechanically coupled. However I see newer Shimano motors can autonomously advance the...

You've got nothing to apologize for – any shop should present a properly assembled and safe bike to their customer. I also don't think it's realistic to expect a mechanic's work to be double checked. Bike mechanics earn their keep. Plus, by who? An owner or manager? Sales staff? Hopefully this...

Worth noting this isn't an REI problem as the title suggests, but the impact of a single careless mechanic who could be employed at any shop.

I love the aesthetics of a proper Dutch-style frame and ride a Liv Flourish for casual upright outings, but as a 200 pounder I've always been shy of carbon. From an armchair engineer's perspective this frame kind of scares me, considering the concentration of forces that come together in the...

I'm sure you're kicking yourself! Sorry to hear it. I've come back twice to a lock I accidentally didn't actually close, and another time I remembered the lock but forgot the key so faked it (just for a quick minute, still risky), and thankfully those times the bikes didn't go anywhere. And I've...

This is good to know. My next project is to remove the Speedhub from my analog cargo bike and pair it with a 500W Shimano EP8 CRG motor on a Yuba Mundo frame. A mechanic from Omnium warned me this was going to blow up the hub if I don't use electronic shifting, which left me shaking my head. If...

I bought a new / old-stock Omina C-Type from Upway over the summer primarily for my wife. A truckload of these had shown up on Upway's website with zero miles on them, and there are two listed on there today (one has a belt!). The C-Type is the step-through version of this frame. It's a heavy...

Hmmm, that minimum height could be a bummer for some shorter bikes, but overall this stand is intriguing. I'm also curious to check out their pneumatic lift at Sea Otter. I had a good relationship with Ultimate Support back in the day, and Feedback has only been an improvement to the product...
