Pretty hard fool
First of all dogs cant back flip on a motor cycle. Some can do a backflip but dogs on a motor bike its hard to picture it.
Tandem bikes are really big and cumbersome, so it'd be really hard. And with two riders onboard - forget it.
Suzuki makes a good bike, however this is too vague of a question. This would depend on what model of Suzuki dirt bike, the type of riding you do, maintenance and how hard you ride it.
The difference is that the mountain bike tube is much burlier and wider than the dirt jump tube but may not be as strong in terms of hard hitting strength.
They have a VIN on the frame but can be hard to find and are not all in the same spot.
Any bike can be jumped but the landing is the hard part. In your case I wouldn't try it unless you have a death wish!
Everytime you come back from a ride. Because I find if you dont the mud and dirt will go rock solid, and will be very hard to get out of your sprockets and gears
rocks/bricks
Hard double flip
no, if you work hard and practice alot a back flip will become really easy to you. You just have to stick at it! Ask someone you know who can do a back flip to help you at first. No, it's hard your first few tries but it gets easier. Ask your friends if they think a back flip is hard. It's not really.
Flip the lever on the side of the seat. That will release the seat. Pull the seat out. The bike only folds one way so if you are having a hard time making it fold then you are trying to make it fold the wrong way. After folding, put the seat back. The handle bars also fold so flip the lever by the handle bars and they will also move to allow you to throw your bike in the back of a sports car.....if you have a sports car :)
