It’s string http://www.stringbike.com/.

Like that is going to last in grit, grime and general pedalling…

Factors that usually cause wear and tear on a conventional chain, like rain, snow, mud and sand, do not affect the safety and perfect functioning of STRINGBIKE®.

ahahahahahahahahaha etc

What a wonderfully pointless idea.

I thought I might have missed something

utterly useless but great at the same time

seen that before, doesn’t look like an overcomplicated method all….

Made no sense until I saw this

Its probably Junk. But I don’t suppose chains looked that clever when the high ordibbary (penny farthing) was the norm

Wow!

Like Hammerschmidt only worse!

Given the hub gear and then all this gubbins, I see no cost, weight or durability advantage.

But, just to be safe and off-trend, I had better start collecting shifters, chains, mechs and cassettes before they become extinct…

If you search on the repack website, you’ll see somthing very similar. Done in the 70s or so.
Search for a user on hear called repack rider or Sumin like that.

I think I can see their major problem – which is well hidden by superficial flaws.

I’m still not seeing any string.

Revolutionary characteristics of the drive system:
springs in the hub move pedals forward assisting the biker to ride uphill

When needed the gear ratio can be adjusted differently at the two sides

Long bike tours are made more pleasant. The tiring effect resulting from the constant friction of metal parts disappear with the quiet and smooth stringbike system.

Any disadvantage?

Technically there is no such a thing, but certainly there are issues that our designers are currently addressing such as how to apply disc brakes at the rear hub.

The current size drive train is designed for trekking and city bikes. Alternative size rear hubs with wider gear ratio are being developed serving MTBs and road bikes.

A 21-speed gear is in the final stage of completion replacing the current 19-speed system.

pretty sure TJ does their PR

This is what I was thinking whilst on the toliet…

Not quite the same. But close enough.

that is truly one of the silliest ideas since slingshot bikes and U brakes

Interesting…shame it’s brought the flamethrowers out already…what would you lot have said about suspension/spds/disc brakes before they were fully developed?
🙄

lets find a problem for the solution !

Am I missing something? How on earth can that work? Or are you just putting the energy in to the system and getting some of it back via these springs?

Rik of Rik’s Bike Shack (aka Blazin Saddles on here IIRC) has one of those buddy bikes. And he made me sit in the passenger seat. It was probably one of the scariest cycling experiences I have had and that was just round the car park at Drumlanrig. Not a good bike.

That said I live not that far from a decent sized river and that HydroCycle actually looks interesting.

Yeah – all that 1% loss in a chain drive really kills me. Does anybody know how their hub freewheels work if they don’t have any metal parts in contact? ISTM that must be the really revolutionary bit, not the string.

As an engineer I feel the need to reach for both the eye bleach and me bombers 😯

skiboy.hahahahaha

Not sure if I’ve seen that particular one before, but such ideas crop up regularly. The only things I know of which use a cable are rowbikes:

that is wonderfully weird.. would like to have a go on one of those!

i cant stop watching that rowbike gif for some reason..! 😯

That rowbike looks quite fun. How do you think it would be on singletrack?

I’ve only ridden one on an indoor test track. A standard SWB recumbent is good fun on singletrack, though, as long as you don’t need to hop the front wheel. Fast and swoopy is good 🙂

Stringbike is an anagram of Big Stinker.

I remember it well, I said “I guess I’ll buy it when it works”

In 50 years someone, somewhere will stumble across it in a museum and think

“Hmmm, can’t imagine why that didn’t catch on”.

As a fairly early adopter of all of those (and of full-sus for XC) I stand my ground.

Saw one of these being used on my local bike path. It’s the future.

I want a stringbike!, if you watch the other video apparently it makes you irresistible to the opposite sex and you’ll have friend coming out of the woodwork.

see a guy on one in Richmond park a few times… proper odd..

no chain to oil, and low maintenance, as long as the bearings and pivots last. I can see the point for city bikes that get no attention.

makes more sense than a hipster powered fixie, anyway.

Slope indicator – where can I get one??? Imagine a world where rides are no longer ruined by not knowing how the steep the hill is 🙂

Been looking at the vids and I think this system would look so good on one of my whyte prestons
