When you have limited space for storage, multiple bicycles may just be taking up valuable space for other things.
If I ever move into a tiny home to roam around the world, I may think about keeping a single bicycle.
Until then, my living space is going to be smaller than storage of my hobbies.
I enjoy riding much more than sleeping or eating and I prioritize my living spaces accordingly.

I'm just trying all I can to simplify my life. And this is a start for me. I also plan on selling off all my guitars, guitar music books, and lots of other stuff. Tired of stuff. I want less around me...less junk.

I'm getting an electric bike for my father-in-law who's been wanting something that's easy to step over and take up minimal space in their house/garage.
His typical ride for them would be trips to the grocery store 1/2 mile to 2 mile away, maybe occasionally 7-8 miles one-way to the nearest fishing pier along the Bay Parkway in Brooklyn.

I ordered a $950 w/shipping, step-thru ebike, 500w, 48v 12.5 ah, about 55 lb. bike, expecting delivery next MON. Of course, I will be riding it first.

Nice! I've demo'd a power-assist bike and while it was strange, being a new thing, it was also fun once I got used to the idea.

I'm just glad at his age (75+), he still wants to go outdoors on a bicycle and go fishing.
I know I will be escorting him for the first few outings, just make sure he's safe in NYC traffic.
Weighing the convenience of electric-assist vs potential danger of excess speed, safety is a big concern, but keeping him active at his age is getting harder every year. If he shows interest, I'm willing to invest and have him try it out.

The ones I've seen haven't had a very high "max" speed, which was lower than a person in good shape could do unassisted. Twenty mph max, maybe? When I was riding regularly I could sprint up to higher than that (like for getting through intersections).

A very good thing to keep him active and out and about.

I think the offficial cutoff for how fast you're allowed to be going with electric assistance is something like 20 mph, so you're right, an average cyclist is very capable of sprinting to and maintaining more than that under their own power.

I think what A is alluding to is that for an old guy who injures easily and doesn't recover very quickly and might not expect an easy 20 mph with the quick reactions required for surprises at that speed, 20 mph might be a tad fast. No biggie.dude's still out on a bike after retirement which is awesome.

As long as it's not on trail, I'm all about it. Commuting, city bikes, etc. All good!

On trails that are on fragile cut sections that need maintenance.... I'm a little torn. Need some more data to prove the extra torque isn't going to ruin things. It's likely not much, if any, more torque than a pro level racer could deliver, but if everyone can apply that much power vs 1 or 2 people, it seems to me that it would assist in an elevated rate of trail damage. Idk, maybe I'm also a little sassy about earning my turns. if I'm being honest.

Be assured a 48v 500watt will not add enough torque to a slightly above average mountain biker to equal a pro. It will not keep up. Ask me how I know.

Are you claiming to be above average as a cyclist???

I'm capable of 160-180 watts sustained power over an entire ride. If I were to double that with a motor... I'd be making somewhere in the ballpark of pro cyclist sustained power numbers. I'm very average for a recreational cyclist in terms of sustained power. I'd like to think I'm better than average, but history tells me I'm very average.

It's not about "keeping up", it's about the damage done from the torque. Big difference.

Yes torque, that thing that makes you spin your wheel without go and kick up dirt. We are talking about the same thing. I was a bit over average 15 years ago. maybe 20 years ago

Among NYC traffic, no bicycle is going to spent much time above 20 mph for significant amount of time.. at least not safely.
This electric bike is a folding bike, not a road bike or race bike; it doesn't need to go fast or sustain 20 mph or above.
It's just meant to be used for an old man to get to his fishing spot or grocery store runs to pick up his newspaper.

I've been commuting on my e-bike to work for a couple months now. Turbo mode keeps my speed above 23mph up the hill without sweating too much.

Mine cuts out at 28mph but I can feel the assist cutting back around 26-27mph. Feels a little like engine braking since it's adding 2-3x power and then 0.

I ride home without assist and I kinda wish it had a front derailleur to give me a granny gear for the hills.

Man falls asleep on recumbent bicycle, wakes up in Bulgaria
Leipzig, Plovdiv (dpo) - This morning, a cyclist from the eastern German city of Leipzig was in for a rude awakening: on an outing on his recumbent bike, the 43-year-old man had fallen asleep and only when he awoke did he realise that he was actually in Bulgaria.
Now, waiting for his flight back home from Plovdiv, Rainer Thiesen is starting to see the funny side of his adventure. “I was really utterly perplexed when I woke up to suddenly find myself in the Balkans”, he reports. “The last thing I remember was cycling a few miles south-east of the city, enjoying the beautiful evening sun. After that, I must have fallen asleep. Just why does this damn recumbent bike have to be so comfortable?!”
While sleeping, the father of three subsequently cycled just over 1,000 miles (approx. 1,700 km) across the Czech Republic, Slovakia, Hungary and Serbia until he reached Bulgaria, where he awoke again on Ruski Boulevard in Plovdiv during morning rush hour.
“Firstly, I pulled over, rubbed my eyes and then went on to ask a passer-by where the hell I was”, Thiesen recounts. “I was completely gobsmacked when he answered: ‘Глупав въпрос! Вие сте в Пловдив.’”

Plovdiv – not so bad after all
After he had come to terms with the initial shock, Thiesen contacted his family, who were incredibly worried about him, had a substantial breakfast, visited some sights and then proceeded to the airport to plan his homeward journey.
Astonishingly, his overnight journey seems not to have taken too great a toll on the amateur cyclist. “Apart from sore muscles in my calves, I feel very well rested. No wonder, though. After all, I have slept for at least 9 hours straight. Oh, and a bird crapped on my stomach.”
Thiesen is not surprised that he made it as far as Bulgaria: “I seem to remember that I was in top gear before I fell asleep.” Since the incident, it has also become clear why the 43-year-old was not stopped even once while crossing several borders. A Serbian border guard remembers, “I heard this snoring noise getting gradually louder and louder but before I had sussed out where it was coming from, the guy had already cycled under the tollgate and was miles away.”
Thiesen’s ‘little spin’ does not much surprise sports scientist Markus Zeil, “This sort of thing doesn’t tend to happen on traditional bicycles, since the upright body position automatically forces you to stay awake.” He therefore advises users of recumbent bicycles to drink plenty of coffee, listen to loud music, take breaks and stretch their legs during journeys, or, as a last resort, to set an alarm clock.

People who ride the recumbents say they're more comfortable than a regular bike. Your center of gravity is certainly lower, so they should be pretty stable. Wider seat, back support. Enjoy your next ride!

Yeah, it's like sitting in lounge chair!!! Pedaling position isn't as efficient, but is more than offset by improved aerodynamics. Top-speed record for unassisted (non-drafting) human-powered vehicle is ~89mph set by recumbent... Just bit shy of Ninjette's top-speed!

I had a recumbent bike before I got my first motorcycle. It is very different from the a traditional bike and there is a learning curve before you can ride safety on the street.

Do you lean when you turn or is the turning a bit different?

Still works like regular 2-wheel vehicle. Countre-steering initiates leaning and turning. Depending upon geometry designed into recumbent, it can be more or less responsive than regular upright.

Actually, every study I could find a few years back said that human power output is more or less constant regardless of what an athlete (note, the word "athlete" takes a lot of variation due to fitness changes over time here) is riding, whether it's a diamond frame bike, a recumbent, or a rowing machine. The important part is that time is given to allow for the rider to acclimate to the new vehicle. Rojo is a perfect example of this in real life.

The aero benefit is a huge reason that recumbent bikes are so awesome, and that's for real, not just internet parroting. The frontal area is small on a recumbent, and the drag coefficient goes significantly down if you're able to mount a windscreen.

Did your last one have boom steer like the cruzbike? If not, get ready for another steep learning curve. They're awesome, but that bottom bracket swings with the steering, which means your handlebars are the only thing counteracting the turning moment applied by your feet. The side benefit is you can steer with your feet if you go no-hand'sies with some experience

We only ever made one vehicle that was a 2-wheeler during my 3 years on the ASME HPVC team in college; the rest were trikes. It was an aggressive geometry, which likely wasn't a smart choice on our part since none of us had ridden a recumbent before. It took me a full month of evenings riding around the workout facility's indoor track to learn to ride the stupid thing. Once it clicked, it was silly responsive and handled SO WELL. We made easy work of the slalom portion of the endurance course during race day.

The important part is that time is given to allow for the rider to acclimate to the new vehicle. Rojo is a perfect example of this in real life. .
For steady-state cruising for miles on end, yes, you're limited by same aerobic capacity VO2-max and FTP (aka anaerobic-threshold) regardless of vehicle.

However, for top-speed, anaerobic max-power output of +2000 watts, you need to recruit all muscle-fibres in legs. The seated position doesn't let you use body-weight to fully utilize knee extensors. Knee and hip flexors aren't utlized at all as they require taunt stomach muscles with narrower hip angle..Resultant more lob-sided seated pedaling motion doesn't allow you to spin up to +210-240rpms where max-power is generated.

"According to these measurements the racing upright cyclist can generate considerably more power (mountain upwards or at a sprint), than sitting on the seat." - http://members.home.nl/vd.kraats/recumbent/pedal.html

There's 'bent group in WA headed by Jeff Wills, a former colleague I used to work with for 10-yrs at Bike'alog. I'll see what kind of data they've gathered for their top-speed record runs. Sam actually had the record @ 81mph for a while. And he certainly wasn't putting out more than 1200-1400 watts. You can find easily dozens of 1-2-P riders at any weekend race that can easily out-power him. Not to mention velodrome match-sprint monsters putting out +2000 watts for a lap.

@choneofakind you are correct about the boom steering will be a new learning curve. Should be a fun time.

For an athlete who is given time to acclimate, their power will be the same regardless of their frame orientation.

I haven't the faintest what a knee extensor is (googled, and frankly, didn't care enough to read past the mumbo jumbo), so I'll just have to believe you on that one. But... I will say some aero recumbent bikes are able to hit massive speeds since they have such low drag. The sounds they make are phenomenal... carbon tub chassis, stiff everything, the whole vehicle thrums, like a tight set of ZIPP's, except louder.



Besides professionals or completely dedicated bike-whores, I've never seen anyone out and about who legitimately could sustain 200+ rpm for any length of time. I work on my high cadence efforts and I'm only smooth up to about 120 rpm when I'm in season. I can do 130 rpm for short bursts on descents, but it's rough and there's no way I could sustain that. My typical average over ride is 90-95 rpm.
