My CG125 puts out slightly less than 9kw. My housemates hairdryer puts out 2kw.
I can't help but conclude my bike would go faster if it was powered by 5 hairdryers!
Even worse than that, a 50cc four stroke scooter puts out 2.8kw (according to Google)
I know small bikes have weedy engines, but it's quite depressing to think that they're comparable to a £6.99 hairdryer from Argos...and you don't need to put oil in or replace the bearings on your hairdryer.
Am I doing something wrong with my calculations? The logic seems inescapable. |

The hairdryer uses 2kw, the output will be far lower, most energy will produce heat and noise..
The 9kw from the cg is its final power output, it would use allot more energy to produce that 9kw and again it would be heat and noise and 40% (if that) final power output to the rear wheel after getting through the drive train e.t.c. ____________________ >RidingSkills<->Tech Tips<->MyBikes< |

Given an engine is 33% efficient, your bike would be more comparable to 14 2kW hairdryers... ____________________ https://www.bikepics.com/members/fuzzbcf/

The only inefficiency in a hairdryer is sound, so about 5% inefficiency I'd guess.
You'd need a bloody big battery or long mains lead to replace your engine with hairdryers anyway! ____________________ Shaft drives rule.  |

Only the same as 0.0000025 nuclear power stations You would only need 400000 CG's to power a small area  ____________________ https://www.bikepics.com/members/fuzzbcf/
