Taga Bike-Stroller
Based on the workhorse Dutch cargo bike, Taga has reimagined it with a child buggy seat up front. Moreover, as well as folding down to stick in a car boot, you can switch it between stroller mode and cycling mode in less than 30 seconds. The standard set-up includes a child seat, basket and sun canopy, but there's a whole catalogue of accessories if you're feeling lucky. €1,600 from tagabikes.com
Kaito Emergency Radio
This Voyager Pro emergency radio from Kaito doubles up on the off-grid recharging options with both a crank handle dynamo and solar panels to keep it powered. There's a USB port too, allowing you tap its juice as a separate power source. You'll find a low-energy LED light on top and the radio tuner can pick up FM, AM, SW as well as weather bands in territories that have them. And if there's no sun or elbow grease available it'll even run on a couple of AA batteries. $100 from kaitousa.com
LightCap 300 Bottle
There are a few of these sort of products available, though having solar charging is less usual. The bottle itself is a wide mouth Nalgene-type in BPA-free plastic with two flat sides to stop it rolling. Whereas the cap has the solar cell, battery and four white LEDs and one red. A sensor switch reacts to light and they claim 15 hours from a full charge. $30 from davisnet.com
