Here in the Philippines, there is a huge surge of 125cc city commuter bikes called underbone motorbikes, so-called because their body frame doesn't have a top tube like normal bikes, its good for inner city quick trips and what have you. They are cheap to own, maintain and use. Mine gets about 35KM/L or about 82.43mi/gal.
And the underseat storage is nice because you have some space to store your stuff, the bad news is you need to open the seat with your key, meaning you'd have to turn off the engine before you can open it.
Thats the general idea behind building a remote seat opener :D
Anyways, below is a picture of my underbone, just so you guys know what I'm talking about
Step 1: What you need...
- you will be doing this at you're own risk
- any damage done to your bike will not and will never be my responsibility :D
Ok with that out of the way; here's what you need
1. First off you'll need an actuator, you can buy this is in auto supply shops, these are the actuators used for central locking systems for cars. I'd suggest you get the one used to open the trunk, its the one with two wires.
2. Cable housing, you can buy this at bike shops
3. Derailleur cable, this is the one with the flat stopper, used for derailleurs (duh!) :D
4. nut & bolt and a washer, to lock down the cable
5. drill, multimeter, soldering gun, some shrink tube
6. six-pack of beer and some chips (optional) :D
