I do like having some stats after the ride. I sometimes go back and look at old routes (I even have sporttracks 3 installed so I can pull up rides from before I started tracking on Strava ~mid 2010). There are times where I'm planning a ride and want to look at a route some friends and I did...

If I don't run them on my non-electric I definitely don't care about them on the ebike. :p I do run a wahoo cadence sensor on my trainer, and the trainer itself does power. I've never bothered with them on my actual bikes even in my roadie days though.

Lots of MTBers downgrade whatever Bosch computer comes with the bike to the Purion 200. Which is similar to the Steps 7000 display my eMTB came with (super minimal, clamps to the bar just to the right of the stem). My only complaint with the Shimano display is it only shows battery as 5 bars...

I've seen rumors over the past few years that Bosch is working on ant+ or it will eventually be included, but nothing has come of it. I kinda assume those are reps or shop owners blowing smoke up potential customers butts to try and sell bikes. I do find it perplexing; the customer base for...

The issue with Bosch (as I understand it) is their system flat out doesn't output ant+ data. So theres nothing for Garmin/Wahoo to read.

Auto definitely confuses it. I never use auto so its not really an issue for me. I've had my giant for 5 years and the only assist mode name I can actually remember is eco. The little giant emtb controller I put on my Revolt has 5 lights for mode as well (they light up from bottom to top for...

I've never found them to be difficult to setup, just tedious. The touchscreen ones are simpler for sure (I've had both 500 series and 800 series, currently running a 530). The good news is you setup your activity profiles once, when you get the unit, and then probably never touch them again...

Looks to me like its a welding failure. Cracked right along the weld on the underside, crack expanded until tube failed. Warranty. Hope they cover it.

Yeah, those tubes look awful wimpy for an alu frame. Aluminum has basically no fatigue limit, so if frame design allows it to flex it will eventually fail. Thats why aluminum frames generally use large diameter, thin walled tubing; makes for a very rigid frame that avoids that issue. The...

Thats generally how aluminum fails. Welding heat weakens metal so they generally break somewhere near the weld (tubes are usually butted, so they tend to crack where the thickened area ends; this is true on steel frames as well). Aluminum needs to be heat treated after welding to restore its...

At least they aren't punishing countries that were smart enough not to vote for it. I imagine the wishy washy language (instead of just calling it a tariff charge) is to avoid government retribution.

The issue with carbon, as a material, is its strength is highly dependent on the direction/type of the weave. An aluminum plate will generally be equally strong no matter how its oriented, but a carbon plate could be super strong one direction but very weak another if thats how the carbon...

Its smaller, but I love my Routewerks: https://routewerks.cc/products/the-handlebar-bag Its not as spacious as the touring style handlebar bags but has a plastic top (with bike computer/phone mounting point) and a rigid frame. Attaches to the bar using a machined aluminum mount that has a quick...

Dunno, lightweight low assist systems seem pretty popular. Part of the issue may be that the more power you have, the more battery you need to actually have a usable range. And battery is generally where most of the system weight comes from. Catalyzt is absolutely right that I'd be very wary...

The ebike market is hyper competitive, so I suspect that if a significantly smaller, lighter motor was easily achievable someone would be making it. There are very likely aspects your engineer friend isn't considering that make it a more difficult problem than you think.
