Pedaling an ebike home

I have a out of shape friend who is thinking of getting a ebike, he says it weighs about 60 pounds. He wants to come along on our group rides that go distances of 100-125 typically into hilly terrain.

My question is, should the battery run out, will he be able to pedal home?

I don't know the ebike he intends to get. I know nothing about ebikes.

Thanks!

In hilly terrain, even with a very conservative application of assist, a normal size battery would not last 100-125 [miles]. Could he pedal it home, not likely.

Why not? You can pedal an Ebike even if the battery run out. I dont see the problem of pedeling it back home. I love my S-Pedelec Test

Thank you. I think it's a problem with my friend more than the ebike he wants to get. He has a nice Trek road bike but he's so out of shape and refuses to do even a little training. His average speed is about 10 mph on the flats and less than half that on even moderate hills. But he still wants to go with us on the long rides and figures a ebike will allow him to do this. Knowing him, he will use it like a motorcycle, climb hills on probably 90% battery power. So, if the battery runs out, he'll probably won't be able to pedal the ebike back in any reasonable time (before nightfall).

I'll put it this way, I'm pretty fit, tour a lot and 60 miles would take me at least 4 hours on a 60lb touring bike with a full suite of gears.... so when your mate's battery is flat halfway, he's stuffed.

It is POSSIBLE to set up an ebike to provide a little bit of assistance, and have the battery last a fairly long time.
And (good) mid-drive bikes don't add any resistance while pedalling. They're still heavier though.

Thing is, many ebikes are still designed for people basically uninterested in riding.
(They buy the bike for the utility value).
Means they're not that nice/efficient to pedal.
I commuted on a $3000 mid-drive bike for awhile. And I got something like 120 miles on each charge.
But I LIKE pedalling.
My average speed is above the cutoff, so the motor basically only worked at intersections and climbs.

At what speeds does your group ride? The slower you go on a e bike the more range you get. If i run my 1200 watt geared hub motor at 100% (28mph) throttle then i only get 14 miles out of it. If I ride at 20mph then I get about 20 miles range. At 15mph I get 31 mile range. Also if he goes with a geared hub then when the battery does run out he won't have the motor dragging him down. That's with a 48v 1200watt geared hub motor. Hope this helps

It's theoretically possible, but in reality, no. Club rides that routinely cover over 100 miles are pretty serious rides, and your friend will find himself far from home and still out of shape when his battery dies. There's only one way to fit in with that group, and that's to get fit.

Have him get a pair of the latest basketball shoes and try out for the NBA.

He would likely be able to get to the place where the group ride leaves from, watch you all go, and then return home.

What he MIGHT be able to do, is locate a scenic and/or purposeful ride with a round trip well under 20 miles, more likely 5-10, that he can do on maximum pedal assist, REMOVE THE THROTTLE, and then gradually work down the assist level and increase the distance, then after a year or so, get an expensive e-bike with a large battery so he can expand his range, then after another year or more, he might be ready to attempt the group ride with a reduced chance of suffering a major heart attack.

Thanks for the info. The group generally moves along at a fair pace. Once we get out of MUP's and into open country, it's a paceline wherever possible. On the flats about 24 mph+ and on hills, it's who can get to the top first.

Thanks Joe, yes, exactly what I'm concerned about, running out of battery. He will use battery power like he was on a motorcycle. (I'm sadly finding, he hates physical exertion) I've known this guy for a long time and he's done me lots of favors so, I try to help him out but finding it impossible now. I take him out on very easy, flat rides just the two of us but it's frustrating. Even at a moderate pace, 12-14 mph, I look back after a few blocks and he's about a block behind. I keep telling him, he has to try to keep up to up his fitness but, he's solidly stuck in his comfort zone.

Yes Nelson, that sounds like his speed. I'm beginning to see, it was probably foolish of me to tell him how nice a long ride with the group will be to him. (in hopes he'll train and get fit) I can't even get out of him what ebike he's looking at but tells me it's one towards the higher end. I can believe this because he does get high end equipment in everything else.

I hope he gets lots of enjoyment out of a nice ebike, and he will as long as he doesn't try to do centuries with a fast group ride. I would encourage the purchase, then you guys can do those short rides together and he will keep up. Just tell him the group ride idea isn't a thing for that type of bike.

Hi Joe that makes sense. And maybe by doing short rides, he'll get enough impetus to increase fitness, perhaps by riding more on the ebike that alone may increase his fitness.
BTW, the group I ride with, we've been riding together since the late 1970's doing all the local criteriums and road races with double centuries thrown in. I just wanted him to experience how great cycling can be.

Thanks!

Sounds like he needs a scooter. Are there gas stations along the route?

I've looked back at some of your other posts... it's not appropriate to say what you are... but it's obvious.

I am not aware of any e-bike batteries that are capable of a 100+ mile range along a route that has a lot of hills. There are a few 50cc scooters that have that kind of range. But to be safe, a gas station would be useful. A guy that struggles at 10mph on the flats isn't going to make a 125 mile ride on an ebike - he better take a gas scooter.

The question was if the guy could pedal back home when he ran out of battery, which had been comprehensively answered when you showed up with some bollocks about tailing a bicycle group ride with a scooter. That's trolling.

Out of shape is still out of shape, but pedaling an extra ~20lbs...

The bike he buys will play a huge role in what it pedals like without power and the range. 100-125 mile rides I assume is a road bike ride. Is that correct? Not many electric road bikes out there yet (Giant makes one), but depending on how much power he uses the range won't even be close to that mileage.

With that said, I have a friend that is having a professional bike shop build him a Salsa Touring BBS02B 750W/48V ride. He regularly rides 100-125, and even 150 miles on his current non-electric bike. He went with the Bafang because it has little to no resistance when pedaled without power. He "IS IN GOOD SHAPE" for his age and only plans to use very low power assist during head winds and hills to help as he ages. Much of his riding will be without any power at all. The Salsa bike will be equipped with top notch components as if it wasn't an E-bike and a 21Ah Panasonic-Sanyo GA battery with an extra smaller backup. The extra weight won't faze this rider, as he is used to carrying full camping gear, but on his last Santa Barbara to Orange County ride he gave all that away to a homeless man in Long Beach. He says it's motels/hotels for the night from now on.

Sure your friend can pedal it home, but at no faster than he can pedal his non-electric bike now; and most likely even slower due to the extra weight. He will easily be able to keep up with the group if and until his battery runs out. At that point he may become a burden to the group if he isn't the independent type that can find his own way home or call for a pickup.

The positive is an E-bike will assist in getting him into shape, but at some point he will have to start cutting the power to progress with his riding ability.

A GOOD rider would have trouble pedaling an e-bike back a lot of miles. They are heavy and do have some drag. Yes I have put miles on e-bikes with just pedal power.

You need to get your guy to ride within his limits.

I wish your buddy well with this project. I'm not a "pedal 100 miles" rider - even when I could, that many miles bored me to tears! - but I can do a good 30-40 without much drama. I have a mini velo with BBS02/52v and it rides fine without assist..the problem is I never want to do it! I'll be curious to see how having the motor affects his riding style; I suspect he'll stick with PAS 1 assist a lot more than he thinks he will. It's fun!

Hi NoPhart, yes, all of the group has top end road bikes, in the 18-20 lb range.

With that said, I have a friend that is having a professional bike shop build him a Salsa Touring BBS02B 750W/48V ride. He regularly rides 100-125, and even 150 miles on his current non-electric bike. He went with the Bafang because it has little to no resistance when pedaled without power.

The major problem with my friend is he's deathly afraid of hills, so he's mentally beaten from the start. So, I suspect he'll use a lot of battery power.

I've come to the conclusion, it was a very foolish thing for me to do telling him about our rides. I assumed wrong when he told me he plays tennis and golf and been riding bikes for decades, and seeing his gear is all upper end stuff so I assumed he was in some kind of shape. But at this stage he can get the ebike and I'll go with him on short rides. I've done about all I can to help him, even showed him the route to his workplace (only 4 miles one way) in hopes he'll get in more days to ride. On that short ride, I realized he's not street smart at all on top of it, so another thing for him to learn.

Hi speedy25, I'm beginning to wonder if he ever will come out of his comfort zone. I've never seen him sweat or breathing harder, even a little. Seems at a certain point around 12 mph he just settles down and does no more.

I'm right there with you, doing 35-50 miles about every other day in comfort and ease because of the BBS02. My preferred level is 4-5 of 9 with pedaling (speed limit set to 25mph), but my gearing is set for about 17mph top gear pace. My bum usually has had enough when I get over 50 miles.

Deep down, I think my friend wants to do his rides "faster" with shorter time for distance. I also think he will use a low level of assist virtually all the time, but he isn't afraid to put in pedal "effort" too. That will get him mega range, because pedaling with effort on any level of assist with the BBS02 drops the watt usage to 50-100 watts once at the speed of that assist level. That means he will likely be flying along at high speeds with little watt usage and bettering his distances based on time.

I've got 100 miles out of my Soma B-Side MTB BBS02B and 21Ah battery using level 4 of 9 and speeds between 14-16mph on my 2spd geared ride (1st is strictly a granny low for climbing hills off-road). 1:1 2nd used as 1st gear is 50x28=1.786 and 3rd used as 2nd gear is 33% higher at 2.375.

Not to get too far off topic, but I'm just about done with my alloy Electra Lux D529 Cruiser. The D529 stands for 5spd 29er. It has a Sturmey-Archer RX-RK5 disc brake IGH with 29er Veloctiy Dually 45OD/39ID rims sporting Surly ExtraTerrestrial 29x2.5 tires. This S-A 5spd has 25% gear gaps and can easily be geared for a 28mph speed pedalec. I'll post up the finished project soon. It's stretched out with Paragon rear dropouts, carbon 29er fork at about a 65* head tube angle and should be able to be ridden with the road bike crowd with ease. But that just might offend "some" of them...
