I did consider that, but I'm not sure if the e-bike will be able to carry extra weight. Currently for short trips I use a manual bike when I don't need to carry anything, so I don't really need to replace that. Will an ebike be able to seat a passenger or two? I am not really sure what the...

I do not, but the tank holds more than 200 km worth of petrol. For daily commute, it is unnecessary to have such a large tank, but occasionally I will be making longer trips. The battery weight is why I was thinking of the petrol/electric system mostly.

I see, that does make sense. What kind of batteries could get about 200 km of range with lower weight? Currently this scooter has a 4.1L tank and a mileage of 56 kmpl (not particularly good). If the hybrid system will be less efficient I would be happy going full electric. If it helps, the...

This seems like a very appealing idea. Do you think it's possible to run that motor off a minimal battery by adding a larger alternator to the original engine? Although I suppose the issue with that is that now the engine is both running with variable RPMs as well as the extra load of the motor...

Quick question on cooling. I'm not sure what motors are possible for this build, as well as what I'll need, so I was wondering about this cooling setup. The original Janus engine has a side radiator on the swing arm, as such there is no cooling in the bike itself. Would adding an intake scoop to...

What is the weight of this motor? And when it says 'air cooled', does it require a fan of sorts? Curious what the continuous torque and runtime of this would be.

Yes, 9999 is often used as a placeholder on many chinese sites. Usually means that the final price is tbd.

The engine on this bike is 125cc, it can make 9.5 hp. The vehicle currently weighs 95 kilograms. I'm not really sure how much power iI'm going to need, since I don't know what the realistic end weight is going to be. I will certainly look into using a higher RPM motor, as well as look at that...

New to building electric scooters. I am trying to convert a Yamaha Janus to a plug-in hybrid to improve fuel efficiency. The weight of having the generator (which will be modified from the original engine) will be a significant increase over just having the electric power train, but if I can use...
