Buying Schwinn 17-Function Bike Computer


In my opinion, this is a very good bike computer for the money. I'll explain.

I've used one of these for 3 years almost every day now and have found it quite durable for my purposes, paved trail riding, 9 miles a day.

As others have stated, the instructions can be a bit confusing and a little thin in places.

Let me offer these 3 suggestions:

The mounting and adjustment of the sensor is not quite as you'd expect. If you look at the sensor itself, opposite where the wire comes out, you will see an arrow in the plastic moulding. The wheel magnet needs to be OPPOSITE THIS arrow. Then, simply slide the sensor (and magnet) down towards the wheel hub (down the fork) to get the sensor and magnet closer and position each for the arrow. I don't recall where I read about this arrow "feature" but it seems to be a closely guarded secret.

The second thing users seem to be having problems with is resetting the distance, DST and MXS, max speed readings. Use the RIGHT hand button to ratchet down until DST is displayed. Then hold down the LEFT button for at least 2 seconds and DST will be cleared. Then, again with the RIGHT button, ratchet down one click more to the MXS (maximum speed attained) and hold the LEFT button for 2 seconds to clear that. This will clear a couple of others like AVG and TM as well, but not the whole thing. You can then press the RIGHT button to ratchet back around to whatever function you want to ride with. I leave mine on ODO.

I have found that dropping the computer can cause a reset as the battery becomes dislodged. Place a small piece of foam rubber under the battery cover to hold the button battery more firmly in place and the problem is solved.

As an aside, I use the ODO reading to tell me when I need to put air in my bike tires (about every 2 weeks). Because I ride a fixed course every day, I record the ODO reading between a couple of mile markers on the trail that are 3 miles apart. When the "apparent" miles covered gets above a particlar threshold, the tires need air. The ODO reading is displayed to 0.001 mile so there is sufficient resolution for this as long as the ODO hasn't rolled over to > 100 miles. FWIW, when the ODO shows 3.005 miles, I need air. After adding 15psi, the ODO reading is 2.994 miles.

I hope users having problems find these suggestions useful from a long time user.
