ASME Human Power Vehicle Challenge 2017, LNMIIT Jaipur First time in HPVC history we made the bicycle which has all-wheel drive & also with the Compactness with great innovation. Aerodynamic Fairing Adds up more stars in vehicle performance & Aesthetics. We get the special achievement award by ASME with 12th rank at national level.

8. POWER TRANSMISSION
• ALL WHEEL DRIVE
• U joint mechanism For FWD
• Semi-Recumbent
• Triple Chain Transmission
• Gear Ratio-4.11
• Use of pre-wheels

9. STEERING & BRAKING
• We are using universal joint mechanism to steer the HPV.
• According to our design, the distance between seat and front wheel is more so to
steer the vehicle easily we are using universal joint.
• As per the rule book our vehicle turning radius is less than 8 m.
• Brakes Front wheel: shoe brake
Rear wheel: shoe brake
