This is a common problem with rebuilt Model Bs. It stems from the two flywheel support arms being too close together. The two arms then pinch the flywheel cage halves together until the arms encounter and pinch the flywheel axle, resulting in a slow or no handle return. To check this theory, slightl...

Plugging into a charger or your computer per Carl's suggestion is probably the easiest solution. As indicated earlier, the Model A,B and C do not have the ability to generate power for the monitor and so will use up the batteries much quicker than a D,E, Dynamic, SkiErg or BikeErg. Turning the monit...

three things to be concerned about: * Electronics, primarily the display which (I believe) is rated to -30F. * Bungee cord stiffness/loss of tension- which will get better as you row. * Clutch engagement, which also will improve as you row but is much less predictable than the bungee cord. So do an ...

Looking closer at the flywheel, the surface texture looks rough, which might mean it's a sand casting, rather than a die cast part that C2 used. So it's possible that the flywheel is also not a C2 part. That would explain the absence of the magnets.

Ah, those holes were put in the flywheel to balance and correct the moment of inertia of the flywheel. Nothing to do with the sensor. Seeing this I am surprised there is no sign of the magnets or the holes for the magnets. Typically we received the flywheels from the die casting company with the mag...

I don't know what the part with the holes is all about. Maybe they had another method of mounting the sensor and some magnets on the other side. Good luck with it.....Jon

Remko, If the magnets were installed they are visible but are small- .100" in diameter and are mounted flush with the flat side of the flywheel. There are three of them equally spaced about 2" from the center of the flywheel. You can just see one of them in 2wheelsforevers pic that is showing the sc...

Remco- Do you have any idea where it was originally purchased? It's clearly not a C2- many of the components look like a Concept2, and the overall first glance is convincing. I recall we had issues of people ordering parts, particularly flywheels, in quantities that were somewhat suspicious. The fly...

Remko- A couple overall pics should be enough. Side view, front, and angle shots. The pic you posted shows one sprocket- the Model B has two. And the configuration of the wire cage and hub isn't right. Any chance of contacting the previous owner to find out how the monitor and pickup were assembled?

Could you post a couple more pics of the machine? What I can see in the photo makes me think this is not a Concept2 product. JonW

There are still Model As out there in use! The wheel weight is butt welded and bolted in place so removal is not recommended. If the spoke nipple is in good shape just reuse it with a new spoke. If the nipple is not ok then it's likely the flywheel will run fine with a missing spoke as long as there...

Sounds like a bug. Wonder if it's adding on the strokes taken during the rest period? In any case you should contact C2.

The monorail is a single piece of extruded aluminum that is hollow in the middle. The track is stainless steel that is adhered to the monorail. Both parts are available- I notice the paint on the monorail is in really bad shape, so you can either replace that or do a disassembly, repaint the monorai...

Also, I was wondering, are you supposed to move the chain on to different sprockets for different amounts of resistance? I've only used it on the smallest one so far, which would give the most resistance I think. That's correct- the resistance or feel is altered by moving the chain to the different...

It's likely a Canadian made knock off. C2 had an authorized manufacturer in Quebec City for a short period of time. After C2 ended the relationship they continued to make unauthorized machines, which this is probably one of. The bracket is not a C2 part, and C2 never used a low flange hub on the fly...
