  • Last year we moved to Sheffield from London, (via Aarhus), and have been struggling with taking Bella (~20kg 5y/o bull whippet lurcher) on our Omnium around the seven hills. Thought I would start a build thread of the 20" e-cargo I'm going to replace it with. (Omnium will be for sale soon too!)

    I've decided to go 20" wheel front and rear. I can't really understand the advantage of having a large rear wheel if the front is small, as it just seems to take up more space (which is at a premium in our small victorian terrace with awkward doorways). A 20" Suntour 100mm suspension fork up front (so poor Bella doesn't get rattled around as much). Low stand over with plenty of space for a long dropper meaning my partner can also ride it if needs be (we had a similar setup on the Omnium, but the unnecessarily high/horizontal top tube meant it never quite worked). Grav grav tyres.

    In terms of electrics: a Bosch Gen 4, Performance line cargo motor and the 545 externally mounted battery (with the option to add and additional external battery in case we go for a longer tour). Custom stem to get the stack height right (I could potentially do away with this and extend fork's steerer tube but that feels like more hassle/danger) Lights F&R, smart system controls. I've not built an e-bike before so this is a steep learning curve!

  • Crumpet in her matching jacket (on the one day of the year it was cold enough for her to need it, she runs too warm for regular use). Now I just need to find the space, funds and trust in the dog for a matching cargo bike.

    Our shopping bike at Omnium HQ is an old prototype with 20" F+R. While there are benefits to the small wheel it's also very obvious it doesn't roll as well as a bigger one.
