In addition you should add this new Biktrix model which seems to be aimed at the up market Watch Wagons crowd https://www.biktrix.com/pages/monte-capro-ultra-details And the CSC ebike ultra model https://csc-ebikes.com/ft1000md-mid-drive-electric-bike-gray/ aimed at the entry/mid tier Rize price...

Slightly off topic from the OP’s question, you claim “ my bikes out climb the Ultra and out last it for the distance.” While that could well be true for the Sondors Rockstar you’re specifically comparing your builds with, the laws of physics and some actual empirical data on e mountain bike hill...

See: Not exactly an apples to apples example, but informative nonetheless, The key is torque at the rear wheel, i.e., how much torque from the motor ends up transferred from the drive tire to the ground. Assuming the specified torque is the static starting torque at the output shaft for a...

For the DIY crowd, the CYC gen2 pro motor kit also uses an ASI controller (the one I bought last April used a BAC 855; you can also order the kit with a BAC 2000. See: https://www.acceleratedsystems.com/products/electric-motor-controllers/bac855 and...

As you have noted, only a limited number of torque sensor PAS DIY kits are on the market with just Tongsheng offering the easy bolt-on Bafang installation experience. I found that another torque sensing DIY kit seems to have evolved into a viable option in the last six months or so, namely the...

This seems close: https://voltonbicycles.com/shop/alation-500-torque/ I've not seen any reviews on this model, particularly their implementation of the torque sensor, which have many have noted, is a tricky thing.

Interesting question. Apparently both Wattwagons and Zen's new models have recently undergone frame durability fatigue stress testing following sort of ASTM/DIN standards at some official TUF/UL testing facility (maybe). Perhaps passing these tests at some level allows manufacturer's to claim...

On the steel pedal axel threads to mitigate galvanic welding of the pedals to the aluminum cranks.

I see Diamondback has introduced several models within the spirit of this Zen design envelope. See: For EBR/Tyson’s first impressions. If you can actually bring in your baseline derailleur version at your initial proposed price you’ll have undercut them by a significant percentage. However...

Question about the different power rating specs of the Archon controllers. My assumption is that the higher power rated ones actually either use higher power rated MOSFETs or more of them in tandem, i.e., that the various models have different hardware componentry and hence the tiered pricing...

But to take advantage of the knowledge of better odds you've just learned, you need to chose the other door to get the improved 50/50 odds. The original choice still only has a 33% chance. This is a classic tenet of the time value of knowledge in decision theory/behavioral economics --- this...

See: https://electrek.co/2020/11/09/priority-current-belt-drive-electric-bike-review-underpriced/ for Toll's review of the Current. I pretty much agree with all his conclusions, but I do have a few minor criticisms. 1. No brake inhibitor switches --- probably a carry over from their Embark...

See: The Electrek guy, Micah Toll, explains the pros and cons of belt drives using his personal Priority Current as an example --- so probably a review to come from him in the near future.

Ergon makes half grips for Rohloff/Nuvinci twist shifters. I’ve found the monochrome display washes out in direct sunlight even at 100% and the lights switched to boost the backlight. Apparently it takes a few hundred miles for the Nuvinci to fully break in --- mine is considerably...

The original contributor mentioned above is adcockj whose original post is appended below. Another post in this same thread describes shortening the stock spring to get a similar result. the stock spring. I used the adcockj double spring approach and it worked well for me. adcockj New Member...

It would be interesting for a rider with experience of both the Innotrace/Archon controller/SW and the Biktrix tuning could share/compare their experience.

I'm not sure I like the look of the bob'd front fender over the full extension design that came with mine, which I thought sure was going to fall off /fail soon when I first got the CC last May. But it's still going strong at the 900 mile mark. For my first ebike I lucked out and chose very...

One problem with it though is that the stock spring is very stiff seemingly tuned for only the heaviest riders; however as per another contributor to this forum (sorry I couldn't find the original reference), by using a combination of one long and one short Kinekt seatpost spring in series...

I agree that the LX is likely to be a good platform opportunity for customization and upgrades. However the number one issue that will likely need to be addressed first is not the motor controller, but the drivetrain groupset if Sondors continues their theme of using the same 48 t chainring and...

Rather than anecdotal seat of the pants impressions of range efficiency, couldn’t you just directly measure it (i.e., WH/mile)? Possibly an inexpensive 20 dollar watt-hour meter Drone/RC people use to monitor their Lipo pack health/lifetimes would work...
