How Fast Can You Tow A Caravan... With A Bike?
Рет қаралды 536,840
Күн бұрынIs this the worst idea we've ever had? We wanted to find out just how fast you can tow a 700kg caravan by bike. Thankfully ultra endurance cycling legend Mark Beaumont was on hand to attempt the world record for us.

@@xristos1250 no, 1hp is 736w, so 5hp is 3680w. I think it's obvious in the video that it was not only stability which prevented him to go faster. A 700kg caravan has a significant rolling resistance and at such a low speed the air resistance is small. Human power is too small for such a heavy transport with rubber tires so I think the speed will remain low. Exceeding 20km/h the air resistance will be significant as well so I think 40km/h requires several cyclists on a tandem to reach.

Geez, they could have at least rigged up a cable actuator from the caravan's brake booster to a lever on the handlebars, or rig it up like a dead man's switch release in case he lost control. If he'd actually got to 25mph he'd have a hard time stopping without being run over. Also they could have messed around with the centre of gravity over the caravan's axle to reduce the load on the towball by moving internal components rearwards, which would then reduce the pitch up of the bike's front wheel (obviously there would have to still be some weight to prevent lifting up the rear wheel of the bike and losing traction). Considering how little time he had with no preparation, Mark still did a really good job!

Also, why not START from some of those existing bicycle trailers for towing your kids around? The ones with 2 nice wheels and a set up to attach to a bike. That way you could build the tow ball between the trailer wheels, essentially giving the caravan another axle to support the weight on. That's where I would have started from. First minutes into this all I could think was "no way can you do this with a caravan with a single axle!". Good fun though... just need an engineer on the team.

Some tips for the next attempt: - Use fat tires at lower pressure, to increase grip and get better leverage. - Swap the front wheel for one with a smaller radius, like 24", to increase weight on the front . - Change the caravan's tires for the skinnier ones you can get, and inflate them at their highest pressure possible. - Use a thru-axle, steel-frame bike. Another option would be to use a Hase Kettwiesel delta trike. With a solid attachment to the frame, a differential for two wheel drive, and a Schlumpf Mountain Drive, you will have no problems spinning the pedals to move that caravan.

As any heavy boat owner will tell you, comfortably driving down the road at good speed requires just the right amount of tongue weight. If you are going to go faster, you need a new mount that will deliver the load to the bottom bracket so both bike wheels are being loaded by the caravan. Then you move the caravan axle forward and backwards until you get just the right tongue weight, which you find by experimenting. Something like 5-10 lbs would probably be about right for the speeds you want, but be careful: falling and getting run over by a caravan at 25 MPH would be dangerous.

Finally, Mark is GCN Staff(!). Strikes me that a few sandbags behind the rear axle of the trailer (either inside, as far back as possible, or back on the bumper), and a sandbag (or, better, lead-shot filled bag) over the handlebars, would balance the hitch-weight out nicely enough that you wouldn't need - and wouldn't be hindered by - the little wheel up at the trailer tongue. Surely there isn't a rule of making the trailer, and bike, a tiny amount heavier? Extra weight may seem counter-intuitive, but it's mass that, once you get it going, will be beneficial to the balance of the tractor and trailer. Tiny cars pulling too big of caravans have proven this out over the decades - they generally can get the caravans up to speed on the flats, but their clutches or transmissions normally fail early.

weighing in with experience at building and towing weird loads on a bike: I built a trailer using a Burley 2-seat and about 100kg of steel plate, what I found while moving a house on its ten foot long deck was to balance the load over the axle to the point where a five year old could lift the front and turn the whole assembly on his own. This way, the standing load on the bike was neutrally balanced on both wheels, and the moving load moved backward on the trailer but FORWARD on the bike (see-saw effect with the ball joint as the pivot). This effect would be mitigated at the front by the rider loading the back wheel maintaining traction and reducing the snake motion. which is caused by loss of traction on the back wheel of the bike and misbalanced load on the trailer. There would be no mitigation at the back of the trailer which would increase the rolling resistance of its wheels by the moving load trying to pull the front up. This is actually an advantage when it comes to stopping. You only use the rear brake on the bike and lean forward to keep the front wheel down since the sudden deceleration pushed the front of the trailer down forcing the front of the bike up, hence total loss of traction. The front wheel is thus basically only for steering as long as you're moving. And yes, 25mph is not beyond the realms of possibility, it is just unbelievably dangerous with a 1500lb static load.
@sergarlantyrell7847 4 жыл бұрын
You can tell none of the people at Guinness are cyclists if they thought 25mph was a good minimum! That said I'm pretty sure I could do better, mostly by modifying the caravan (so it has it's own brakes and balances about the rear axle).
@Ed.R 4 жыл бұрын
I'd love to try this, I have so much experience towing things with my bicycle. Would it be allowed if the tow hitch on the caravan was modified? It needs to apply the weight just behind and below the saddle on the seat tube. Bike is far too light, you need a much heavier old steel framed mountain bike like mine, 18kg min. Also with heavy weights it's a totally different style of riding. You have to be patient and keep applying the power eventually the speed will gradually increase. If you try to get acceleration it will feel unmanageable.

@@lexvandewal8856 700kg once moving is no bad deal on level ground. As you've experienced the weight becomes irrelevant until you want to change speed. The problem with the caravan is the large contact patch of the tyres and aerodynamic drag. In Mark's case he was wasting most of his energy in the side to side movement.

Impressive. But the average speed (of trials in each direction) was calculated incorrectly. True, it’s the average of the two numbers, but not your rate over the total of the 50 m “raced”. Rate = distance / time. Distance in each direction was obviously the same, but time was not. At d=25, I get time for the 11.093 run to be 2.476964233 seconds. The other direction was 2.535239834sec. (Actually should use their timing numbers, which presumably are not that precise.) So, the average speed would be 2*50/(t1+t2) = 9.977 km/hr. ( rounded). Still, pretty impressive. So the distinction of the average of the two speeds needs to be made with the average speed. I’m wondering if there are more established speed records where the accepted protocol is to make a timed run over a stretch in both directions and establish the average of the two speeds, and not the average overall speed, as the basis for the record. Anyone know?

As an engineering tidbit, it may be easier to tow, if you set up an arrangement where the axle of the trailer's jockey-wheel is the attachment point for the bike-to-trailer towing arm, so that the jockey-wheel and the rear wheel of the bike are constantly pointing the same direction, preventing the trailer "tail" from wagging the bicycle "dog", and the weight of the trailer can be more completely decoupled from the tow-arm and bicycle...
