What is the top five things i need to take on a 4 mile mountain bike ride?

Question

through lots of rocks and stumps and other junk

Answer 1

yourself, your bike, water, and maybe a patch kit in case of a flat. you shouldn't need much else as 4 miles shouldn't take too long, even through rough terrain. if you want to go super slow you could bring a little snack, like powerbar or something.

Have fun!

Answer 2

Water, flat repair kit. Maybe a snack if you plan on stopping for a break. 4 miles isn't very long, especially on a bike, so you shouldn't have any problems running out of resources.

Answer 3

1) Spare tube, quicker than patching and doesn't weigh that much

2) patch kit for when you get a second hole

3) frame pump

4) Fluids to drink

5) Cell phone if service is available - covers the unexpected

Answer 4

Water, spare tube, first aid kit, cell phone, snack.

Answer 5

1. Bike

2. Helmet

3. Gloves

That should be it for a ride that short.  I wouldn't bother with anything else.   Repairs would take longer than a 4 mile run back to the car, so I'd leave the repair kit there.
