Batch eFT.3 Review: A 28 MPH fat tire e-bike built for the streets

This one is outside what Retrofit Relay covers. The site focuses on home energy upgrades — things like heat pumps, insulation, air sealing, and rebate programs that lower your utility bills or qualify for incentives. An e-bike review, however well done, isn't tied to your house's energy use or eligible for the kinds of home efficiency rebates this site tracks.

For context, though: the bike in question is the Batch Bicycles eFT.3, a fat-tire electric bike built more for paved streets than off-road trails. It comes with fenders, lights, and a rear rack, uses a 750-watt motor with pedal assist up to 28 mph, and has a 720 watt-hour battery. It's priced at $1,999, discounted to about $1,799 through September. None of this connects to home energy efficiency or rebate programs, so there isn't a homeowner angle here for this site to summarize.

If you're looking for news on heat pumps, insulation upgrades, or rebate deadlines that could affect your own home's energy costs, that's the kind of story this space is built to explain.
