Tunturi E303 exercise bike tension knob won't turn

Recently had a knee replacement and dragged my exercise bike (about 15 or 20 years old) out of the garage and cleaned it up.  It worked fine but after a few sessions the tension knob became harder to turn and is now stuck.  I am riding with very little resistance and desperately need to add more fore my rehab.  I know where to order a part but need instructions on how to replace the tension cable, assuming that's what is needed.  Can't afford the $200 repair bill I've been quoted!  Any ideas?

If it is just the inner cable and you don't need the housing then Napa Auto parts and others sell a universal cable kit that you can cut to fit and comes with a crimp tool for installing the square end on it.

SOURCE: no change in resistance

IF you have the one i have, there is a knob with two connected arrows and a plus and minus sign. turn toward the plus, more resistance, turn toward the minus, less resistance.

SOURCE: tunturi exercise bike stuck in high gear

Detach power cable. Remove the side panels to reveal the wheel drive's left side. Here you will see some electronic circuit - the gear engine. A small fuse (glass thing with metal in both ends) is most likely blown. Buy a new 350mA fuse at an electronics store - and your gear will be working again.

SOURCE: have need parts to a tunturi ergometer / exercise bike

It looks like the only cable FitnessRepairParts has for Tunturi Ergometers is a speedometer cable for serial numbers greater than 474100.

How do I replace the battery on Tunturi E414. Thanks.


Pull the entire electronic box out of the bike housing. You'll find the battery compartment cover in the back.
