30lbs might be possible ... but it will obviously depend on the starting point. Grin's new 340w bottle battery, Bafang 3xx hub motor (front or rear), BaseRunner controller a CA with MFS, PAS disc/sensor and some wiring is going to be 12-13lbs. You'll also need to get creative in the...

52v, Phaserunner, and a GMAC ... I'll bet it moves really well. I hope you keep those V brakes and pads in good condition. I like the CA mount out in front of the stem. I did much the same for my builds, only I used a minimal setup with a U shaped strip of metal and one pair of bolts on the stem.

1) I'd really dig into the CA and look for any error messages and the ramp of watts used (looking for a specific point where it reverts to 0W). I'd also put a meter on the battery connections and look for the possible voltage sag mentioned under load. 2) When you connected the throttle did you...

Yes but I think "just" 350w of battery goes a lot farther (or is a lot less of a concern) on a 36lb bike with no throttle and good gearing as compared to heavier ebikes with more motor and a throttle that aren't as rider oriented.

I've used the large (3/8" I think) padded hooks and simply installed them into exposed studs at a height that holds my ebikes against the wall with most of the weight still on the rear wheel. Ideally this works best on a bike without a rear fender but in the case of one of my bikes with...

Tom, That's not really relevant (but still impressive) ... the comments were about the startup characteristics and if I remember correctly TS also had serious problems with the early units. But like any effective organization they sorted them out and have a reasonably well respected product today.

If I could only have two of them ... in an ebike lineup in a bricks and mortar store, I think I'd sell more of the green and grey. If I was selling online only and primarily though my own website I think white and grey. White and grey would appeal to most folks (or more accurately no real issue...

That all sounds good. As long as it all fits snug without interference (and remember that the fork will compress a bit when the nuts are tightened) you'll be fine. I've experienced this - dropping a motor into the forks sitting upside down, everything looks good and then having a small issue...

If you are talking about "regular" thin flat washers that would simply behave as a bit of a spacer then no, not having then isn't likely to be an issue (assuming everything like the disc brake rotor lines up properly and nothing is rubbing). But if you are talking about tabbed washers that are...

I think having an alternative to the highly integrated commercial mid drives is important for a lot of folks. I only wish there was some common control code for these setups. Yes I know that you actually could graft a Grin Cycle Analyst into one of these mid drive setups ... but it's not an easy...

There are actually many different reasons or benefits of a throttle ... beyond the "don't ever want to pedal" shtick on a Super 73 style ebike. For example in my case I really enjoy riding a bicycle in a traditional manner (ebike or not) at higher cadences, but in and around traffic in my...

I think the apples to apples comparisons would be more in the $900 range but your point is still valid, is "better" engineering worth twice the price? I guess that totally depends on what you value. The old analogy - do you drive a Chevy or a BMW, and why? Is size, fit and finish important? If...

Wouldn't it be great if there was a CyC North America entity? A local (west coast) warehouse for the quick turnaround of small parts, a few accessible tech support folks with the Cyc Asia engineers on speed dial/Zoom. The problem is that once the products become popular this model inevitably...

Doesn't surprise me ... there seems to be a general shortage of 36h rims in wider (30mm+) sizes from all sources. --------- I'm going to be building up a new hub motor based rear wheel for my day to day bike. Unfortunately it's a pretty big jump to start doing wheels yourself (but relatively...

Hmmmm, So many interesting things. - power from the 9C motor, and the impact on the ride. I've also been curious about the differences between that direct vs. a geared hub motor setup. - efficiency from the different wheels between the Ogre and BC. Aside from slight differences in rider...

Even the hyper weight conscious pros have dabbled with front suspension. There have been front suspension setups used on the pavés in the Tour de France and Paris Roubaix classic.

When folks are saying "gravel" ... what do you mean, as there are a number of different gravel surfaces. I have a lot of fine gravel covered paths/trails, the kind loved by joggers but hated by skateboarders. These multi use trails are usually hard packed with some fine loose gravel on the...

700c is not the same as 27.5" but they are close. 700c wheels/rims are slightly larger in diameter, but there are wider tire and rim options in 27.5". 27.5 is the same wheel as 650b. You may find that a bigger (fatter/wider) 27.5" tire is actually very close in circumference to a narrower 700c...

Depending on where the controller is (is it really integrated into the battery holder/cradle or is it just "integrated" into the bike frame) you'd need to find the same physical format ... the ones integrated into the battery holder are different physically than those that are intended to be...

Normally when you see an integrated controller setup it's part of the carrier or cradle for the battery. The battery lifts out of the cradle and the controller stays with the bike (it's wired in). There is also a small circuit board - a BMS (battery management system) that is built into the...
