Things on two wheels

It occured to me that I do have an obsession with things on two wheels. Something mystical about them. I guess just seeing them balance on two wheels and also its is the most fundamental way of mechanized travel. An engine and two wheels, simple and raw energy transfer. No wonder that no car has the acceleration to a match that of a race bike's.
These are my two mountain bikes. The Scott Thermoplastic Carbon-fibre Endorphin with mostly XTR parts. The Norco fireball with XT parts in Singapore. Both bikes are amazing and have very different characteristics. The fireball having made of aluminum flexes more than the carbon fibre bike. The carbon bike is more responsive with its stiff frame but can be a little uncomfy on the bumps. Mat love and Visco Boy always try to hide their envy of Endorphin.



















These are pictures of a remote control motor bike I created for an undergrad design project. The design was done on Pro-E and prototype was constructed on a SLA machine. The actual prototype as you can see jumped off a ramp and kept its balance on two wheels. The project was KICK ASS! The wireframe and solid models you see are screen shots from PRo-E and you can also see the actual prototype.

I like this one, the bike is doing a wheelie..

This is the 3-spoke design I chose for the front wheel. Simple and classic.

The design for the chassis was important. It houses the batteries, motor, transmission gears, remote control system, servos and attachments to the steering systems. You can see the annulus for the gyroscope system on the rear wheel. The lead annulus spins ~4.5X faster than the rear wheel. It has a plastic clutch that allows the annulus to spin even if no power is sent to the wheel. The annulus stabilizes the bike.
The bike is attempting a stunt now. Doesn't it look like Ducati Monster??
You can see the exploded view of the bike. Also you can see the resin parts from the SLA machine. It is amazing..the machine is like your laser printer. You send your CAD drawings to the "3-d printer" at the click on your mouse button and a day later, you have your parts!!!

This bike runs on gas powered engine and is made by an italian company and costs an arm and a ball.
