E-TUBE PROJECT Cyclist 4+

Like many of the reviews read I ended up with a very expensive single gear bike when the firmware upgrade required upon first connection commenced. After about 10% of the upload, the app reported an error and the bike became totally unresponsive.
To reset the system I had to remove the battery (in my seat post) and after about a minute reconnect restoring function to the gears. I then went into my Bluetooth settings to forget the paired device before reconnecting using the passcode I had entered prior to the upgrade.
This time the app connected and the upgrade was installed successfully.

After all that initial disappointment, I did enjoy being able to customise my bike and refine the settings for each control.

I was not expecting much from this app after the reviews I have read, and confess I didn’t use it at first after switching my old mechanical groupset for Di2.
However, frustrated at not being able to get the gear alignment right using micro adjustment on the levers, I tried using the app.
Oh, how I wish I’d done this sooner. This made setting both the front and rear mech alignment so much easier and I now have a groupset that shifts seamlessly.
My one frustration is that connecting via the app is rather temperamental.

Very useful tool. Connects every time. Essential if you have Shimano STEPS E-Assist
