Simon Cowell is getting back on the horse -- or, more accurately, back on the bike ... this after breaking his back on one of these damn things less than a year ago.
The 'AGT' host was spotted cruising along on another electric bicycle Sunday in Malibu with his girlfriend, Lauren Silverman, and his young son, Eric ... who all had bikes of their own. Interestingly, though, it was only Simon who seemed to be using a motorized version.
You can tell it's an electric bike by that little box stuck to the down tube of the frame -- they help propel the bicycle forward with more acceleration as you pedal, giving you a boost.
The fact Simon's once again riding one of these raises eyebrows at first glance. Of course, Simon practically shattered his spine on this exact type of model back in August ... when he was testing out a new electric bike of his, in none other than the courtyard of his own home.
If he almost got paralyzed from just that setting ... this one here -- out in public, along a windy bike bath with other riders zipping by -- is definitely a lot more dangerous, potentially. Still ... it looks like he's got the hang of it, but seeing this does make one worry a bit.
Simon went through a 6-hour emergency back surgery at the time ... and has undergone intensive rehab since then to get back on his feet. Welp, now he's back on his ass.
Be careful, SC!!!
