Actually it wasn't the grease. I tweaked the motor somehow during reassembly. It didn't go together well. I fixed it by taking it apart and carefully sliding it back together again. You can also have brake rotor rubbing and this contributes to a similar problem. And I'm not sure you are...

In SB1271: 26302. (a) and (b) would obliterate the entire ebike rental industry in the state until they replaced their existing fleets with compliant batteries. Realistically that means new bikes, not just new batteries. The same goes for all existing product in the retail sales channel but...

Standing on the pedals AND looking behind me. And maintaining braking pressure.

Not really an ebike story at all.

And if I add a racing stripe to my jersey thats another 10 :). Shaving my legs is +5 but then I need to wear a bag over my head and thats -15.

I have seen people use 2x4's. Strap them to the frame and let the bike bounce against some soft wood vs. powder coated metal. Actually what I saw was two lengths of 2x4, notched at either end, and the pair planted between the two bikes' top tubes. Then the two top tubes were clamped together...

Nope thats not what that is. I have KMC chains with and without that coating. Chains with that coating on look more like a dull, bare steel. Not shiny like a nickel-plated one. EDIT: I found a pic of one: This pic was taken in 2020 and the chain is STILL on the bike, about 1300 miles...

1Up is usually the go-to recommendation in this category insofar as a purpose-built ebike rack is concerned. Maybe you aren't using the heavy duty one? Their 2" Super Duty rack with the second bike tray is rated for 200 lbs total. Myself personally, I use a motorcycle rack which is rated for...

When you are riding, do not look behind you while steadily, strongly applying the brakes. No matter how accomplished of a rider you think you are. Cracked some ribs on this one. Didn't even scuff my clothing since I pile-driver'd straight down into the pavement.

I think you are focusing on the wrong thing here. You use gears to get up a hill, not extreme power. here lookit: That is a 28T front chainring. And on the back, I am using a pie plate cluster with a big 51T cog. I can climb ANYTHING on pedal assist with no trail at all, never mind...

Don't be hesitant... you have a complete guide handed to you on a silver platter :-). You can't screw up. Luna no longer sells the Black Box tuner. I have one of the early ones and for years it was my go-to until I discovered the Speeed app, which gives a whole new level of convenience. I...

That could be all tuning. A 30a Luna BBSHD with a 52v battery works out to 58.8v x 30a = 1764w. With a 48v battery its 54.6v x 30a = 1638w. These are measurements at 100% battery charge so thats only a peak, but still you get the idea as to the motor's happy place. You will have quite a bit...

I haven't been talking about built-in motors like the M620 because those are found only on bikes with bespoke frames. Bear in mind the M620 has exactly the same torque rating as the BBSHD. 160 Nm. Its torque that matters, not watts in terms of your to-the-wheels result. However, 160 Nm is...

OK this explains a lot more. If you heard that from a Bafang engineer, then I suppose thats a reliable source. But really what you are describing borders on unique. And the fact its such a well-used motor... that is a level of hard use and longevity you will not get with a competitor's...

The solution to that is to adjust the cadence programming so it can't run away from you, which it does on the factory tune. Then you just dial back the pedal assist to a lower level than what you need to maintain your preferred cadfence level. So you are always expending effort to maintain...

Take a peek at the Microshift too. Now that I have it in hand, it looks pretty good. Installing it this weekend. Can be had for right at the same price as the Sunrace. Neither Sunrace or Microshift clusters have given me even the slightest bit of trouble.

Yup it sure does. I am currently trying out a Gustavo chainring, which is a US$35 clone of the Lekkie. Just to see how it behaves. Its powder-coated vs. anodized so it appears to wear immediately, but thats just the powder coating wearing off. It also has a little less offset, but only a...

The BBSHD is pretty much the standard for reliability for this kind of DIY motor. Everything else, long term, tends to be more maintenance and less long-lived. A Cyclone is certainly more powerful, but way less sophisticated (no pedal assist never mind torque sensing). A Cyc X1 Pro is more...

My experience with a Cyc X1 Pro told me I would not touch the Photon until its had two years in the market, and it turns out that was a good move. I said the same thing with ToSeven and sadly it doesn't look like we will need anywhere near that long to judge them.

I've never broken a chain, either, across many bikes, miles, years etc. I do always carry a spare though. The whole chain not just a few links. And a breaker and a pair of pliers. I've spent too much time sitting roadside fixing things I never expected to break, to settle on half-measures...
