I've done 12 miles, but left the batteries at work (intentionally). I've done 6 miles with two SLA bricks attached on a couple of occasions.
what's longest ride you had to pedal due to a problem?

My worst ride was on my 120lb Norco A-Line when it ate the chain on the electric drive side. I had to pedal all the way home (7.5 miles) on human power alone. It was like 70*f, a nice warm spring day… started out cold though so I had heavy jacket and moto helmet, and was cooking. The hills get real big the closer I get to home.
That's the #1 reason I will ensure my next build (1) is a folding bike (take it on the subway) and (2) has narrower wheels (take it on the bicycle rack on the front of the local busses).

Walked about 1.5 miles through the single track trail and that some more when I broke my chain on my mid drive. The walk of shame with a hub motor wasn't never bad. Usually just 5 minutes of walking. I'll be running with a spare 6 fet controller with my heavy bike. There is no way I can pedal a cromotor when things go bad.

It is doubled and then connected to the paracord. It is surprising how it smooths the tow. No problem with snapping and my trike and me are over 150 kilos. If you just use a rope the snap from relieving the slack is really bad.alsmith said:

Agreed, I use DD motors on a few kick-bikes and never felt there was much if any drag when pushing them around unpowered. I wonder if the people who report serious cogging with DD motors might have something going on in the controller? Possibly a slight regen setting or something resembling mildly-shorted phase wire? If that's even possible?

BUS? You bet!
i put my mbike on a city bus when a cop gave me a ticket for not having pedals
Cop told me to walk it home and i said NO I'll take the bus.
Now have an ebike w/pedals, but they are mainly to please the cops. i ride a regular bike when i want exercise.

I've used the elastic type once for car towing- not my rope - it was the wrong sort it was like bungee cord elastic and boy did it stretch..........
Mine was one of those solid bar type that has springs at the end to stop the hard shocks, and (the best thing) it stops the towed car hitting your back end (which is why I got it). Definitely recommended, never thought about using to tow a bike but it should do the job.

The RR of my trike with moto tires/rims is definitely more than the RR of the roadie I used to have, but not enough to matter to me-- see, it's still about as aero as the roadie, and the RR difference is only noticeable under 10mph.
I recall that when Justin was testing the cogging of various DD motors, he found the Falco motor had the most cogging despite it's cost, and that most DD's increased the RR of a wheel about as much as moving from road slicks to MTB tires. Not desirable if you're pedaling all the time, but with even miniscule levels of assist the drag is eradicated... I can't wait to get my controller-- I expect that when I'm on multi-use paths I'll keep myself limited to 250-500 watts, which is still quite a lot of power... unless there's a very steep hill.
Can't wait to get this thing together. The bike shop that's a block away from home is very ebike friendly, as at a couple employees have ebikes and one rides his ebike exclusively-- a 350W BionX assist. Which already feels superhuman. I can't wait to have a maxed-out vented cromotor behind me.

My perception of cogging is that resistance increases with speed. So the resistance of a dd motor is minimal at 5 mph, but boy, just try to pedal one up to 20 mph.
Since my pedal home is always uphill if I go to town, the real problem is the weight of a bike. It just feels like pedaling a 60-80 pound bike up a hill. Uggh.
In my previous post, I forgot to mention my worst walk of shame. Riding in the mountains, I rode down into a canyon about 1500' deep, on a seriously rocky rough trail. Climbing back out the other side, I couldn't hang onto the bike if I rode faster than 5 mph. That bloody rocky. Soon I cooked the halls, and was pedaling home smelling winding laquer roasting.
I was very fortunate, that a paved road was nearby, so I only had to push the bike up about 750 vertical feet of the rocky trail, with a grade of about 25%, then ride back to the car on paved uphill of about 5% for 5 miles. Cogging? Who cares? You could barely even walk on that damn trail. No way I could pedal it.
Later on at the house, I noticed most of the motor cover bolts had backed halfway out of the motor, and my derailleur was also falling apart. That's how rocky that uphill ride was. Shake and baked the bike.

Not really, the trail is simply too rough to ride. It's open to motorcycles, but you rarely see one on that trail. Now I know why.
But if you want a good uphill ride, I got lots of good places. Emory pass is still my favorite, the one we used to do the gravity races on. It has nearly the same profile as Alp d Huez. 10 miles of 8 -10% grade. Not Pikes Peak, but a damn good hard run.
Those wishing to look at Emory Pass, It's West of Truth or Consequenses NM. On Highway 152.
The one I broke down on is called the rim trail, near Cloudcroft NM.

OK DM. Up to you (or some other ebiker in your neighborehood) of course!

Had an EVil thought. Might not one "fat" ebike (wheel tire) maybe handle many terrains better? EG:

Someone needs to invent some electric shoes for when my legs give out on the walk of shame because I could no longer ply the pedal of pain.

I'm the same. I got maybe half a mile and luckily was near my brothers house so left the bike there while I spent a couple of days recovering. If I could strategically place all relatives and friends .........

Riding a bicycle at 20mph sitting upright needs serious human power anyway.
I often ride my BionX systems around 30km/h (almost 20mph) without any assistence and I can not feel any drag (I assume it is there, but definitly a lot less than 10W). I do this either because of legal reasons here in the EU (I am able to configure the 48V BionX systems to assist up to almost 30mph, if I want to do so) or "just for fun", because often I use the motor in my electric bikes only for accelerating and going uphill.
I just don't want to become to fat and lazy and in winter some serious pedaling is also needed here to stay warm.

I pedaled a geared hub motor ebike 13 miles when the controller on my ebike-kit died as I left work. Luckily it was summer and the sun was out late. Took me twice as long and I got home just after dark. I should have just took the bus.
I love my recumbent but with only a single speed and the weight, my motor essentially acts as gearing. Couldn't get along well without it. That said I've done several half-centuries on my hybrid with big 40psi semi-nobs... half that XC. Great fun but leaves you hungry!

Does pushing count on this thread?
Previously posted that I had to cover about 10 miles to get back by pedaling, but for pushing...
I was building up the 2WD back in 2011 and suffered two rim flats almost back to back. The first had me about 3.5 miles out, but the second was worse at just over 8 miles. Nothing more humiliating than pushing a bike, especially one I built
After that I started double-wrapping the rims and moved away from thin tubes: Cloth-type, like Velox - followed by Polyester tape, initially I used what came with the rims, but I may have switched over to Mr. Tuffy. The layer facing the road is Stop Flats 2 on the front tire and Panaracer FlatAway on the rear. Switched to Kenda Downhill Tubes - mainly because they are commonly available, and they have been rock-steady, filled partly with a bottle of Slime.
However none of these treatments will stop a 1/4-inch lag bolt from entering through the sidewall and penetrating all the way down to the rim as what occurred on my road trip to California. Pushed the bike about 100 yards to find some shade in 100°F++ weather and fixed it on the spot cos the nearest town was 10 or 20 miles away.
I don't wish that upon my enemies.
