Re: My recumbent cargo bike

Thanks Donn -- good info. I agree the weight distribution on the bike is important, as is keeping the drive train as simple as possible. Excess maintenance requirements definitely are a burden, especially if you actually put miles on the bike. Suspension is getting more important the older I get (wh...

Re: My recumbent cargo bike

Looks like this coming winter might be better than what you had last winter. Even up here in MN (Twin Cities) with snow on the ground we've gotten in some nice December rides. You probably don't bother with studded tires down there! How many more miles before you're willing to say that the mid-drive...

Re: Nucular electronics - complete kit for ev! [beta]

rowbiker , it is milliseconds. How did you use them? My torque tester happy now, it works how it should be. Also i want to add torque-proportional control, not only human watts, this will help to start from zero. Thanks for "Time" explanation. BTW, I'm impressed by your ability to peg 500 watts of ...

Re: BEAMts Torque Sensor...Figured it out!

vmbray, Fantastic bit of engineering -- and a good find on your part. I'm doing something similar, except that instead of using a BEAMts, I'm getting my torque signal from strain gauges I've placed elsewhere on the bike. Your use of the new 24 pole PAS sensor from Grin sounds like a great idea. Coul...

Re: My Sun Trip Bike, Back to Back Tandem Trike with Rowing Generator, Pedals, +Solar

How has the PASD "Row Bike" setting in the new CAv3.1 firmware been working with the rowing action? Which PAS sensor are you currently using on your stoker bottom bracket input assembly? Are there any addition tweaks to the current 3.1 firmware coming out in the near future or can I proceed with the...

I'm not an expert in rowing, but I've heard epic distance endurance rowing event pros end up with chowdered hands afterwards even using the best gear they have. Oh yeah, I've had my share of that even on not-so epic rowing events! Part of is you said is that on a boat you are using your hands to ma...

Re: KMX Trike Front Suspension

I bought a frame kit 6 months age and started putting it together Sunday. May I ask where you got the KMX kit? Utah Trikes or directly from Asia? Adam recommends Utah, which is probably the safer route. If ordering "the kit", does one specify the model, or are they all the same at the kit level?

Re: Warren's 350 MAC mid-drive (finally) recumbent

Thanks for the info. I assume that if Tesla et al. switch from the 18650's to the 21700 format, things could change in a hurry. I'm fairly heavily invested in the 18650 format, but like most of us, have been habituated to spending way more money on batteries than we should have to. I'll very likely ...

I feel your frustration. Until the day before yesterday (Saturday), I hadn't gotten a decent ride in since early December. The same Polar Vortex plaguing you in VA was, of course, hitting us up here in MN. It was the road conditions that were mostly the culprit though, not the temps. Even with 4 row...

Good suggestion, amberwolf. For the purposes of doing an autopsy, damaging some of the parts may be acceptable, unless it prevents useful test results revealing the original failure of parts in the controller. One thought I had is that the bottom (non-component side) of the controller, which faces t...

The "Copenhagen Wheel" ebike (unified rear wheel hub) uses pedaling in reverse to 'turn on' regen braking. In my limited experience riding this configuration, it works very well.
