Error message on recumbent bike

My RPM sensor was defective and I replaced it with a similar one from ebay and that did the trick:

Horizon Tempo Treadmill RPM Speed Sensor Reed Switch 2 Terminal Wire 002267-B (flat version)

This problem can usually be resolved by replacing the overlay keypad.

Possible causes for a dead battery or it not holding charge

1. Battery has lost its ability to hold a charge (dead battery)
2. Charging system on unit has failed (battery cables, alternator, or alternator control board)
3. Stuck key on the display is causing a constant draw from the battery.

The bike is no longer sold and the company went bankrupt in 2014, so neither support nor parts are available from the company. Try the results of this Google search regarding the E1 error code:

It is very difficult because there are two main versions of exercise bikes, so I've picket two of each type. If you prefer an upright bike the Schwinn 140 Upright Bike is the best pick, if you're more into recumbent bikes the best option is Nautilus R514 Recumbent Bike, both of them won the 2011 best exercise bikes.

1) Take the batteries, put new batteries , clean the contact batteries very well.

2)find the cord that move the plate magnet in the base wheel
3) Pull the magnet plate back to the wheell, now the error will be disappear.

God bless you
