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...

^^ I like this option and have seen similar demonstrated in video tutorials. What I think is going to be a (literal) hangup is the way the brake line gets wedged in over the hump of the motor as it passes through the bottom bracket area and into the downtube. It's not pinched, but it shifts up...

I thought I was going to post the final build pictures and be done with this thread. But nope! Nothing to do with the motor, but I installed the Jones H-bar handlebar, and my hydraulic line is too short! 😠 The handgrip position is in roughly the same place as the flat handlebar it's replacing...

@stompandgo thanks for the subtle hint! ;) I added a speed-read summary to the top of my post. It sounds as if this most of this procedure is not necessary for motors from any of the other regions (Korea / Japan / EU), that either version of the eMax software (cabled or Bluetooth) could make...

Worth noting that if you look at my wheel circumference, in the first eMax screenshot I had Shimano set it to 2192mm, which is my actual rollout. However now that I've got access to modify this setting, I divided my actual rollout by 1.6 (the ratio of 1.6 kilometers to a mile) to get 1370 mm. I...

Crib Notes Summary: A walk-thru of my unlocking a Taiwan-region Shimano EP8 motor, purchased from an overseas vendor via AliExpress. The motor is speed-restricted to 16 MPH and 400W. Firmware version is 4.1.8 and is software-locked, preventing Shimano USA tech support being able to switch it to...

I have a happy update to this saga! It works! This all has deviated quite a bit from the original post that kicked off this thread, so I'll write something more specific and detailed in the Shimano forum in the coming days. Here's my attempt at keeping this update brief: My AliExpress EP8...

I've been cursed with collecting a couple too many bikes, and a pretty compact storage space (I won't pretend it's a garage, let's just admit it's the bike shed). About two years ago I just couldn't take it any more and invested in a system called "Space Rail" from a UK outfit called Stashed...
