But you don't have the same transmission as the wheels are part of the transmission. Smaller wheels are not as efficient - more rolling resistance. You also need to send more chain which is not as efficient. You don't have the same position and lack multiple positions offered by drop bars. The frame is not as rigid and absorbs pedal energy. In the end ...

The factors that affect bike efficiency are: Weight Mechanical power train Losses Aerodynamic Drag Rolling resistance For a touring bike, the difference between a folding and regular bike are all lost in the noise. Smaller wheels tend to have higher rolling resistance and the bike might be a bit heavier, but for touring it just doesn't matter that much. ...

You could put a disc fork on, but by the time you bought the disc fork and a decent front disc brake, it would cost half as much as that bike is worth new. You would also need a disc-ready wheel in the front. This would probalby bring the cost to 3/4ths of the cost of the bike. You're better off installing good rim brakes (which are essentially on par with ...

It's slower because of the difference from a road bike; much heavier, fatter tires, limited gear choice. Upright ride position is not aerodynamic. I have a Giant expressway to which I added metal fold pedals, Brooks B67, Ergo grips and Marathon tires. It's for ride to store, short tour ride after bus or train ride or just a fun day on a bike. You can ...
