For me I’d like to try the Boardman gravel bike with Fazua motor. That might well be the best bike at Halfords but wouldn’t be the best bike for everyone, as sjpt says.
For me it (and ignoring price) it would be the Raleigh Felix Step-through hub. But then, we've already got a 2nd hand Raleigh Motus step-through hub. My bike buying priorities have changed a lot over the years.....
I want something to put my grandson on the back and nip about town, 1200 to spend. Have to keep it in the house. Ideally wanted something smaller than my cyclamatic.
You can make the Cyclamatic a lot smaller by adding folding footrests and either quick release clamps on the stem to turn the handlebars inline with the wheel or carry the right sized allen key on a sting or something to do the same.
