Agree, the FX+ 1 looks good on paper vis-a-vis many DTC offerings — with the added benefit of a large dealer/service network and a company that's likely to be around for a while.
Kudos to Trek for warning customers up front that the throttled FX+ 1S version isn't street-legal in California (by virtue of the option to increase max assisted speed to 28 mph).
Question is, do they sell it in California anyway? Guessing they do since that doesn't stop other brands, but will check the next time I pass the Trek store in Encinitas, CA.
The Velotric Breeze 1 we just bought for my wife in Carlsbad, CA is also street-illegal for exactly the same reason, but nary a word on the product page or from the local dealer. Bought it explicily for its ability to switch between torque- and cadence-sensing assist on the fly. Would gladly have accepted a legal Class 2 to get that, as she'd be fine with a 20 mph limit, but Velotric doesn't offer that option.
