>>1152473>why would you want to pedal with in inefficient circular chain ring?Because we are talking about marginal gains that don´t actualy do much.
A oval chainring will not suddenly make you 5 km/h faster, good training will.
After all, the limiting factors are usually not your muscles, but your cardiovascular and respiratory system.
>op get an ebike with a gas turbine range extender>gas turbineWhile a ebike will certainly help on the uphill, a gas turbine range extender makes not much sense at all.
It is expensive, inefficient and will not add much range for its weight on a bike.
You could as well add a additional battery or use a larger one.
