Maintenance Instructions V900V900

1. Wipe the bikes down with a soft cloth after each class. Sweat is highly corrosive and your bikes will deteriorate quickly if not regularly cleaned.

2. Spray the bikes. To help protect the finish and components on the bikes, lightly spray the bike with Aero-Clean which has an antibacterial component but most importantly a component that breaks down sweat, which stops the build up in the little difficult to get at places. Products like WD 40 or other silicon sprays also do the job but keep these off the handlebars and saddle, wipe off excess fluid with a soft cloth afterwards. Aero-Clean, has an anti-bacterial plus a component that breaks down sweat .

3. Visually check the bike over after each session - does everything look as it should? Are there any parts that look damaged or out of line? Adjust if necessary and replace any damaged parts. Do not use a bike that is damaged in any way. If in doubt contact the Instyle Technical Hotline.

4. Check the stem and seat-post clamps,  are they loose, or over tightened? Are the stem or seat

post raised above the safety line?

5.  Clean seat post & handlebar stem. Loosen quick releases and pull out either stem from the frame and clean with Aero-Clean or WD40 etc. When replacing ensure internal clamp is aligned with frame to allow stems to be re-inserted (turn quick release or nudge with finger to align)

6.  Setting / Tuning resistance levels. The resistance knob should be free moving, if the grub screw set in frame under resistance knob is in too tight , this may not occur.

 Tools Required :  2mm allen key

7. Saddle Adjustment: Saddle tilt (backward/forward) can be adjusted by 6mm long allen key under saddle, ensure saddle locked tight.

Saddle clamp locking to seat post (round silver) 5mm allen Key  should be tight  in middle of saddle frame. (loose clamps cause saddle frames to break)

8. Check brake pad. Is it loose and free moving when resistance is off, if flywheel is not straight a grinding noise can occur when resistance is applied.

9. Adjust the  resistance. When brake pad is worn done the 10mm nut on resistance rod can be adjusted if needed .

10. Check security of all clamps and nuts. Starting at the front of the bike check that all nuts and bolts are tight, pay particular attention to flywheel nut ,  and saddle clamp bolts .

Tools required: 17 mm spanner and saddle requires 5mm allen key

11. Check the toe straps for wear . It is important that the toe straps are kept in very good order. Replace the strap if you see any signs of wear. Check the strap at the point it threads through the pedal and also where it threads through the buckles. Important - do not tuck the loose end into the buckle.

12. Check the crank bolts. Use an 15mm socket set to tighten the crank locking nut on either crank, loose cranks cause grinding noise and wear down edges of bottom bracket eventually causing you to have to replace the Bottom bracket and or cranks

Tools required: 15mm socket set ( thin walled)

13. Check the pedals. Make sure the pedals are securely fastened into the crank arms. Prolonged

back-pedalling may cause the pedals to unscrew from the cranks and is not recommended. If the pedals have unscrewed, use a 15mm open-ended spanner to tighten them. Note the right pedal has a right hand thread (turn clockwise to tighten) and the left pedal has a left-hand thread (turn anti-clockwise to tighten).

Tools required: 15mm open ended spanner

14. Check the belt tension. If under resistance a slipping motion occurs the belt has insufficient tension, larger more powerfull cyclists may need more belt tension. Loosen flywheel security nut (17mm spanner ) and use a 5mm allen key to adjust the belt tension located in the frame in front of the flywheel security nut. Only turn the adjusters a quarter turn at a time and ensure both left and right sides are adjusted equal amounts. If not you will change the angle of the flywheel which may cause noise to occur when resistance is applied.

15. Check the flywheel security nuts with a 17mm socket on a monthly basis

16. Resistanse knob is removed by allen grub screw under knob grease the inner workings annually. To replace align knob so grub screw goes into channel on knob, press down slightly and do not over tighten grub screw, if knob does not move freely, grub screw is over-tightened .It is only a locator

18. Check bottom bracket. The axle that goes through the frame, together with the bearings (called the bottom bracket) is the one part of the bike that takes the most punishment. Instyle uses only the best quality parts and a bottom bracket should last up to 2 years before it needs replacing. To check the bottom bracket, take hold of the crank arms and see if there is any play in the axle area. If the crank arms are unstable and there is sideways movement, the bottom bracket needs replacing.

This job requires specialist tools and is best done by a cycle mechanic or an Instyle engineer. However, if you wish to do this job yourselves, we are happy to provide detailed instructions and the appropriate tools.

19. Check flywheel bearings. The freewheel should run smoothly at all times. If you can hear any abnormal grating or grinding noise coming from the flywheel area, or if the flywheel moves from side to side, the bearings may need replacing. Again this job may best be done by a qualified cycle mechanic or Instyle engineer but we are happy to provide detailed instructions if you wish to do the job yourselves.

Note: When changing flywheel or working on flywheel bearings take full belt guard off (inner & outer) before trying to remove flywheel (saves your temper and inner chain-guard from breaking).

On re-building ensure inner chain-guard is tightened up and aligned with two allen bolt holes on front leg.(Easy to get in wrong position and have to take it all off again to re-align the inner chainguard)

20. Annual full service. Once a year we recommend you arrange for Instyle to carry out an in depth service and safety audit of your bikes. During this visit we offer full maintenance training for new staff
