Horse VS Bike

Could a motorbike or moped of exactly 1HP keep up with a galloping horse and if not, why not?

ms51ves3: why does it need 500 miles? Are you teaching it how to be a piston?

I'd say not.

1hp equates to the work 1 horse can do in 1 day.

Thus a horse galloping will only be able to gallop for an hour or so before having a rest (for arguments sake) but could canter all day.

Thus a 1hp bike would be able to canter with the horse all day, but couldn't increase speed to match that of the gallop.

Alexio, are you trying to fill up the new server or something?

What i can add... a horse at full gallop is akin to riding a bike with knackered suspension, no brakes and very worn head bearings.
And it sometimes stops for a crap.

Power to weight ratio?
Even a moped weighs 120kg, + rider at over 90kg (i'm quite heavy Embarassed

) = 210kg.

Horse weighs = ?

Thing is, after riding a 6/8bhp moped (not sure which) for work, i'm not convinced i can outrun anything on it - so god knows how i'd fare with a 1bhp moped!

Random extra thought: Friction of tyres rolling over the road surface will be greater than that experienced by the fleeting contact of the horse's feet as it gallops.

well the 1.7hp insanity 749 is about 30mph..31 at a push.

A horse is.. well...

Too many variables.

I was led to believe that horse power was based on lifting a weight or something, but I could (probably) be wrong

1 BHP isn't actually the maximum amount of power a horse can output. It's the average amount of work a horse can sustain indefinitely.

R. D. Stevenson and R. J. Wassersug published an article in Nature 364, 195-195 (15 July 1993) calculating the upper limit to an animal's power output. The peak power over a few seconds has been measured to be as high as 14.9 hp. However, for longer periods, an average horse produces less than one horsepower.

Things that move using legs normally have much better traction, acceleration and off road ability than things with wheels, but pay for this in a lack of top speed. So i expect a decent horse to make a 125 look stupid up to 30mph, but race horse top speed is about 45mph?
