Bike...engine vs pedal power

[DaveK]

Its been years now since i wanted to do an extended road trip, Mongolia and eastern Russia are my ambitions. I had always planned on taking a motorbike for the trip, something along the lines of an XT600 or even an Enfield...dirt cheap bike being the only option. But i have recently thought about using a push bike instead. The main reason being that I would be almost completely self sufficient, save massive amounts on fuel costs, and a push bike is very unlikely to break down. Wouldn't need to worry about carnets or crashes or major break downs or even how far it is to the next fuel stop. I could also use things like public trains and cheaper flights etc etc

However, i have a passion for motorbikes (ride an R1 atm but that would change) and cant help but think it would be amazing getting to ride every day.

One of my thoughts was to use a cheap motorbike, and if the costs are too high or the brown hits the fan i could sell it and get a push bike and continue on that...

The honest main reason is cost, I could travel for double the time with a push bike, and a budget of £7000 could last me a year, in fairness it could take that long to get that far....HELP i cant decide
