Here are a few key eBike features that commuters find essential to everyday all weather riding.
Integrated means the front and rear lights are wired to run off the eBikes battery, not with batteries that you have to replace, or yet another thing to have to charge up.
A fully enclosed chain guard is common on Euro commuters because they get rain - lots of rain, all the time. Dirt and grime carried by water is the chief enemy of an exposed drivetrain. It is like sandblasting your chain and gears when exposed to rainwater on the street that is full of dirt.
Although not a replacement for a primary lock, these "cafe" locks are a great second lock - and to keep someone from just riding away with your bike when you pop into a cafe for a quick minute.. There are accessory plug in chains that can provide sound security - or use to lock the rear wheel and a Ulock on the frame and front wheel.
