does this computer include the sensor and magnet? will it work on twenty inch tires?

Yes it has a sensor and a magnet, and will work on a 20" bike. I am very pleased with this system.Norm

Yes the product has a sensor and magnet and can be programed to various wheel sizes.
392468
Yes, it includes everything needed and it can be programmed to accommodate pretty much any tire size.

The computer includes everything you need to install it on a bicycle. My bicycle has 26" tires and we installed the wireless Protege computer on it last January. It works perfectly and I've had no problems with it and I am a regular biker, logging about 50-60 miles per week.

The magnet can be placed anywhere on the wheel as long as the sensor can detect it's passage (within a couple of mm). There is a chart provided with the speedometer to determine what parameter value you need to enter based on your wheel size.

It should work. Get on one of the forums and find out how to get into the TPMS learn seting. You will have to start at the right front and work your way around. If this does not work you mite have to let the air out of the tires and refill them and start the learn setting agian. The tire shop could not get them to read, I got the magnet and was done in on time at all. This was on my Corvette so I think the TPMS are the same. Good luck

It takes a 23c tube a tire if that helps. It does have the flip flop hub to add both, fixed and freewheel cogs.

The principle of this gadget works on a magnetic sensor, the magnet is attached to the spooks of a wheel and the sensor which is wired to the reader is attached to the fork of the frame. As long as the magnet comes within 5mm from the sensor it will read as one turn of the wheel. So it does not matter whether you fix it in front or back of the back. One point to note, you need to punch in the code which is based on some calculation on the size and thickness of the wheel before it can give accurate reading. This code is not given in the package. I saw it from some kind hearted soul who contributed it on one of these feedbacks. Hope this help.

My bike wheel including the tire measures just under 24 inches... like 23.5...will this do? Has anyone measured from the wheel anchor to the tire contact patch on this device in the smallest radius configuration?

This bicycle speedometer is designed for a spoked wheel. The magnetic sensor is designed to fit a bicycle spoke on a 26" wheel or larger. I don't own a scooter but scooters I see in my neighborhood are smaller that 26". I am all about innovation but getting the sensor and magnet in the right spot on the scooter wheel and fork would be your first challenge. The next one would be getting the computer setup for the scooter wheel diameter. A local bike shop worth their oats might be able to help figure it out.

Hi there,Yes, during setup you can select wheel size to ensure an accurate read. There are 10 different 26" wheel settings, its almost certainly compatible.

The magnets should come with the sensor. If not Garmin or Bontrager have sets. The cadence magnet on the crank arm, Bontrager has a nice one if you don't mind pulling the pedal and the wheel magnet for the speed half of the sensor either is fine. Be aware that the Bontrager does have a face side that needs to be pointed at the sensor. Pat close attention to the gaps, the closer the better.

Had the tire shop install mine when I had new tires installed. They will have to program it to your vehicle. Most places have the device to get your vehicle to recognize the sensors. Some vehicles allow you to self-program by deflating/inflating the individual tires. Search the Internet for your vehicle.

All the tire pressure monitor requires to activate is a strong magnet which is essentially whats mounted on your car to activate it every time your tire rotates. Not some special part # from the car dealership. This magnet is great for corvette and should be for any other vehicle out there.

The speedometer will work on small wheels, I have one on my golf cart , follow the calibration instructions and proper mounting of the magnets on the wheels. I mounted my magnets with epoxy on my aluminum wheels and works perfect. I use a different tach which works fine on single cylinder engine. Hope this helps.

No sensor included. If you do your own brakes, just monitor how much pad you have left and change it before the sensor gets tripped if you want to save a few extra bucks. MB sensors are not too expensive. BMW ones have a long wire attached and it runs like $30 to replace, ouch!

the wheels need a spot to mount a magnet or maybe on the rotor? It doesn't have to have a battey but it will help. Idont know what the smallest wheel that can be programed but that is obtained by measuring the circumfrance of the wheel

YES. It will work with 24" wheels, as well as 20 & 16, and the larger wheels found on road / racing 'style' bicycles. If you go to YouTube there are instruction videos for this model... as well as on the actual Sigma site, there is a virtual model where you can play with and familiarize yourself with the functions. The instructions come with some numbers which you can enter in for your particular wheel size. I decided to take a cloth measuring tape and just wrap it around my front wheel. The measurement I got was about 10mm different than what was in the manual... but by measuring your tire yourself, you get a more accurate reading on the computer. YES.

I don't see why not. You'd just need to locate the sensor on the back and put the magnet on a spoke, adjust and ride til your heart's content. Perhaps the only issue would be distance of sensor from the actual computer. But I can't imagine the unit is that sensitive.
