The Bionix Prime Fit (often associated with the DP brand) is a classic "manual" exercise bike known for its dual-action air resistance and lack of electrical requirements. While an original printed manual can be difficult to find today, the following guide covers the essential assembly, operation, and maintenance steps common to this model and similar Bionix/BIONFIT air bikes. 🚲 Getting Started: Assembly Basics

• Clicking pedals → Retighten pedal to crank arm.
• Squeaking → Apply a drop of light oil to the tension knob shaft or pedal threads.
• Loose feel → Check stabilizer bolts and the main axle nut (requires 14mm wrench).

1. Safety Instructions

• Consult a physician before starting any exercise program, especially if you have heart, back, or joint conditions.
• Maximum user weight: 110 kg (242 lbs).
• Assemble on a flat, hard surface. Use the included leveling caps if the bike wobbles.
• Keep children and pets away from moving parts.
• Do not use outdoors or in high-humidity areas (e.g., near a shower or pool).
• Stop immediately if you feel faint, dizzy, or pain.

• Speed
• Distance
• Calories
• Pulse

4. Adjustments

• Seat Height: Loosen the twist knob, slide post up/down, retighten. Do not exceed the “MAX” mark.
• Resistance: Turn the tension knob (usually between the handlebars or on the frame) clockwise (+) for harder pedaling, counter-clockwise (–) for easier.
• Leveling: If the bike rocks, loosen the locknuts on the rear stabilizer caps and rotate the caps until stable.

• Apply a dry lubricant (not WD-40) to the pedal threads.
• Check the tension of the drive belt. (The Bionix Prime Fit uses a maintenance-free belt, but excessive squeaking may indicate a need for adjustment.)
