Another welcome from the UK, 40mm square 1.5mm or 16g is one of the most forgiving materials for a trike frame, it is relatively cheap , welds well and many home builds have been constructed with this.

We are a friendly lot on here and will try where possible to help , we all love photos, take your time and choose your build , the multi pack of plans ate value for money , by mixing and matching a hi spec trike can be built .

Our 20/20 tadpole e-trikes are built from a variation of a streetfox with the warrior USS and disc brakes added .
This has made us a couple of versatile trikes , with the added extra of electric assist for the times the going gets tough,
Current project is a folding trike that will fit in the back of my new estate car.
