Easy to take care and maintain bike I never had my own bike. I don't know it's pluses or minuses. Now I need to use one so have to get one. Please tell which brand is easy to maintain, not costing arm and leg to have. Easy to change wheels, rubber part etc. Thanx!
Items reputed for making a bike easy-maintenance:


Internally geared hub (ie no derailleurs)
Enclosed chain case to keep the chain clean
Puncture resistant tyres (which can still puncture, just less often)
Somewhere clean and dry to store your bike at room temperature


NOTE the only bikes that are zero-maintenance are rentals/bike loan schemes, and race bikes that come with a team mechanic.  Both cost money.

Items reputed to increase maintenance requirements


Super light race bikes
Suspension on bikes, both front and rear
Derailleur-based gears
Rotary grip-shifters for changing gear
Bikes stored outside in the rain and cold
