Yeah, THAT, ain't going anywhere under pedal power.Fabian2 wrote:The only downside is if the engine fails, then you are stuffed, because the bicycle weighs 40 kilos with engine, and the 3 trailers that i currently tow, for all the spare parts and tools weighs around 80 kilos, plus rolling resistance.0 -
It certainly does go places. It just that inclines don't favour human power
That's a fair correction - Take 30 kilos off the trailer total when towing 3 trailers.
By the numbers, each unloaded compact trailer weighs 8 kilos or thereabouts and the main box trailer weighs 20 kilos unloaded. Around 20 kilos or so for tools, spares, ect
Full 6 trailer configuration weighs in at 80 kilos give or take a bit0 -
This thread is ace !
Honestly the integrity of that piece of engineering looks about as good as Ryan Giggs would have been if he'd been filmed in the act ! You carry a whole raft of spare parts in case it breaks for god's sake is it that crap ? Even old british cars never came with that !
I was always under the impression that motorcycles were just that, motorised cycles, so what you're trying to achieve is anyone's guess as a honda c50 would do everything you've listed 100 times better, plus you can even pedal it and pretend you're a keen cyclist

Undo the bolt that holds the cable. Does the derailer spring to the limit stop?
I not sure it will bunny hop well lol.0 -

Wait, so you're claiming your bike alone WITH 3 trailers weighs 40 kilos.
So I'm assuming your last nonsensical post means bike minus the tree trailers loses 30 kilos.
But, if we remove the weight of the trailers, then we lose 30 kilos.
Hmm, let's see now, 40-30 = 10 kilos. So your bike with the engine on it, weighs 10 kilos.
So, your bicycle, with the engine, and all those lights and god knows what else on the handlebars, weighs 10 kilos, or 22lbs.
That is REALLY impressive, that's right down to the weight of a professional XC racing hardtail.0 -
not having motorised assist on hill climbs certainly means you are stuffed, as it will take 3 hours for a decent hill climb using low range crawler gear with pure pedal power.
I am not a masochist and would refuse to spend 3 hours struggling my guts out getting nowhere.
Though it's never happened, if the engine fails to operate and i am not carrying a spare, and there is a decent hill climb between me and my place of residence, i would simply refuse to pedal.
My course of action would be to call a tray tow truck using my roadside assist membership and have the bike and trailers transported home on the flatbed :-)0 -
your maths is messed up
Bike weighs around 10+ kilos possibly 12 kilos as it's a Deore spec bike.
Engine and layshaft system and chains weighs around 15 kilos.
All the other components weigh around 10+ kilos
Last time the bike was on the scales it weighed in at 36 kilos but i've added some more gear since then.
Box trailer weighs 20 kilos unloaded,
Two compact trailers weigh around 16 kilos
Gear carried weighs around 20 kilos
3 other compact trailers weigh around 24 kilos
I really don't think of the weight as on flat ground it's quite manageable to push it along with pedal power, especially so on bitumen.0 -
On Bitumen you say?
I do declare, your stated weights vary quite a lot, depending on which side of the argument you want to put across, don't they?
Marvelous. I wish my bike got lighter if I was trying to prove a different point.0 -

Yours doesn't ? Didn't you realise that's what they're supposed to do

come on sonic, you know the rules, dont hijack a thread and send it off topic, we are discussing the importnt business of a bike that is too heavy to be pedalled so it isfitted with an engine which makes the bike too heavy to pedal so it is fitted with an engine which makes the bike too heavy to pedal which is.................................0 -
Yeah, but it's magical, the more you bring up the fact that it's too heavy to pedal at all, the lighter it gets!0

generally i get overtaken by cyclists, and on hills when using motorised assist, a cyclist is still faster.
It's not about the speed. It's about getting there - not stressed, not sore and uncomfortable not overly exhausted and most important of all, getting there with a smile on my face when other cyclists are sitting down; sweat dripping and looking moments away from medical assistance.
My rides are more scenic as i'm not concentrating about the physical struggle when getting to a location0 -
my fave thing about it is that when the engine is running, the pedals are spinning, which should make for interesting results if your foot slips off the pedal.0
-
So, these 300KM in a day rides you're on about. Ho wlong does that take exactly? Let's take a guess at 10 hours. Because frankly, 10 hours on a bike is a long time indeed.
That means you're travelling at an average speed of 30kph.
Magical.0 -

so it isnt as fast as a motor bike and is slower than a bicycle?
sounds utterly websters, and i mean that, i really do.0 -
Re: sheepsteeth
You need to reverse your assessment: with a one way bearing, when the pedals are turning, the engine is running ;-)0 -
And to think of the thousands people spend to achieve such weightlessness, and all you have to do is that ! It should be a faith, Crudology or UCI witnesses perhaps ?0
-
This is a very important point to make when complying with the law ;-)0

So, that's a NO.Fabian2 wrote:I can't answer any more questions on that, because i have a sense of where this is going.
What you seem to be implying, particularly by skirting the issue so inelegantly, is that no, you cannot use the engine without the cranks rotating.0 -
after all, i also happen to have an association with legislators :-)0
-
I am not implying anything, other than my motorised assist bicycle complies with the law and and relevant safety codes regarding bicycle use0
-
Well, answer the damned question then. When the engine is turning, can your feet be stationary on the pedals, without the crank arms rotating?0
-
I refer you to my above posts regarding such .
If it helps, when the engine is not running and the rider is dismounted from the bicycle and the bicycle is moved forwards, the pedals do not turn ;-)0 -

but what happens to the cranks if the engine is running at a speed suitable t propel the bike forwards?0 -
Your answer will be found in my posts.0
-
suffice to say that my bicycle can be operated in a safe and effective manner, compliant with local legislation regarding motorised assist bicycles.
I wouldn't put my own safety at risk, nor anyone else0 -
no it wont because the answer is that the cranks willbe spinning and we both know thats not particularly safe0
-
The situation you have described would not be considered by a manufacturer wishing to design and sell motorised assist bicycles ;-)0

fabian2
right I'm not being funny but you are weird, each to their own and everything but lets face the facts here...
a) you have no idea how to set up a rear mech and came here for advice, you diapered with advice from a well respected forum member(s)
b) your bike is slower and heavier than a bicycle slower than a motorbike,
c) you are very annoying
d) i don't like you
these are the facts and i will have to declare myself out!
