Lugging a Motor, Why it's Bad

[kevinmccune]

Another Pashley Prospero will be arriving from England for me to convert. That customer is putting in the order today. It is getting custom rims, fenders, and a custom paint job, Amethyst, in other words it is purple. Nobody has a bike like that. I will paint the motor, chainguard, and cranks. The lady has money and likes purple.

don't have money,like purple too!

Since my new Yamaha can display cadence, I finally know what my preferred cadence range is. 50 to 60! Slower than I'd guessed it would be. I hope the mid motor won't be harmed by that cadence (yes, I shift!).

Rexlion, this is too low. A big part of the battery charge goes to the ambient as the heat because of low motor efficiency at such a cadence. Please try pedalling at least at 70. No harm to the motor if you pedal slower but pedalling faster will make your knees thank you. Just a gear down.

Curious if you Rholoff leaks oil and if the oil ever needs to be changed? Personally, I'd love to have one on my bike as constant chain maintenance is a PITA.. That said, I'm going on 2,000mi. on my 9 speed ultra powered bike on the original chain which has yet to stretch past .5

Rohloff recommends the oil be changed every 5000km. I change mine a bit more than that. My hub did leak a tiny bit, but after Rohloff reduced the recommended oil amount by half (from 25ml to 12.5ml) it stopped leaking. Bafang Ultra here.

I thought it meant someone who is laminated.

A similar miscomprehension is between a "racer" and a "racist"
There was one of the Discworld series novels of Terry Pratchett set in the Last Continent (it was Australia for us). A failed wizard Rincewind was asked if he were a racist. He said: ‘Racist? Definitely! I can race like no one else when I'm running away from danger!’

My ebike has the bafang ultra motor and if I stop in 9th gear and then try to take off in that gear, the bike will wheelie and it's mr. toad's wild ride. It's not any better using throttle. Similarly, if I MUST stop in a high gear, I turn the motor off to start out again but pedaling with no motor assist in 9th is brutal, can't be done on an incline.

try shifting a little more weight forward to prevent wheelies,sounds like you are on the verge of snapping something,or just downshift,diesels will put all kinds of stress on a drivelines when the motor effort doesn't match the speed ,rpm output,maybe you can program the controller for less torque at low cadence, we always had trouble with broke axles when trying to start a heavy load in an inappropiate gear.

A lamer is a person who has to make up imaginary difficulties to imply they are somehow superior.
Like operating a derailleur.

Same with a KMC e8 chain @2850mi.
Oil leaks are reported but I've yet to see any with 4000mi on one Rohloff and the same 2850mi on the second Rohloff. I'll be doing an oil change soon around 3000mi.

I've only been caught in 9th gear on a grade once or twice. I'll do the get off, raise the rear wheel and shift it to a lower gear routine now but it's extremely rare. With a canbus ultra motor, you can't change any motor parameters. Couple that with a touchy throttle and starting off in 9th from a dead stop is a really bad idea.

What I would do sometimes is use walk mode... it's a steady predictable rate and much easier on my knees than pedaling.

I liked Tiffany Aching, Moist, and Bloody Stupid Johnson. I have seen some of his bikes.

I’m about to get laminated.

It is thankfully a rare Cartesian condition that only happens in cases such as when a sheet of plywood falls on a worker as the steamroller is passing.

Bloody Stupid Johnson invented the bike with a Pinon Box to a Belt to a Hub-Drive. Hint, you only need a belt if it needs something stronger than a chain. But its hub-drive!

I've been laminated twice, the first time through no fault of my own. My advice is to avoid it if you can.

[PedalUma]

avoid it if you can.

Yes, like the three lovers seeking a little privacy inside the hydraulic cardboard bailer. Lamination is not preferred once, let alone a second time like @Jeremy McCreary , but a Cartesian-way of being is so less complicating with only the X, Y to deal with and not all the multi-dimensionality of a complex natural world. See Forest Euphoria, reviews.

Some of these low cadence riders think that they're not getting a good workout unless they're bench pressing the pedals.

I would not feel so all alone; everybody must get laminated.

Nothing like a good lamination before a show.

I purchased a designated small crock-pot. A degreased new chain is hanging to dry in the sun. I also got a big bag of bio-degradable soy wax pellets, used for making candles. The wax just finished melting in the pot. Then I will immerse the new chain in it. I will install it with a new cassette today and it will never get dirty or need lube and will make the new cassette last.
