Class three bike with speed restriction feature?

[mrdaddydiamond]

Looking for a good lightweight class-3 e-bike that has the ability restrict the speed to class-2 speeds when my kids use it, but unlock its full class-3 speed when I use it. Any suggestions?

Most known brand ebikes will ship as a Class 2, and you can un-lock it for Class 3. A few things to note though. If you can lock and un-lock it, so can your kids. The internet has a how-to for everything. I'm sure some ebikes can be locked via a set code but I have no idea who sells such a ebike. As much as speed is fun I've found a regular Class 2 to be plenty for most general riding. I rarely take both of my Class 3 ebikes over 20mph. What is your intended use for this ebike?

My 70 lb 500W Surface 604 torque-sensing hub-drive commuter with throttle came with a 20-mph pedal assist cut-off, but my dealer gave me a 4-digit code to use the display to set it anyway I want up to 35 mph. The 20-mph throttle cut-off's not adjustable.

I also get the need for speed from time to time. Fooled around with 30+ cut-offs for a while but eventually settled on 28 mph. Plenty fast enough for this utility/beach bike.

Pretty academic, though. Between the high air and rolling resistances involved, it's pretty hard to pedal this bike past 22 mph or so on the flat in still air — even with highest assist. In practice, the only time the 28-mph cut-off comes into play is on steeper descents.
