What can we say? We spent months and month trying to find a frame that had our requirements with no joy, so we asked a big well know frame manufacture to build us our own. Thye laughed when we said how many, but after begging they agreed on a sample order of five! We received them yesterday evening and we’re delighted.

Our requirements were:


170 mm strengthened drop outs but QR type to facilitate our 15 mm solid axle with bolt (or your std QR wheel)

Heavy duty rear stays

Flat down tube cross section for Hailong/Dolphin type batteries

3 bottle lugs for easy battery mounting

Big triangle in frame, for big battery packs (that’s why HT not full suss)

Big and easy in frame routing access for wiring

Quality mat black finish (so good we’re not going to paint again)

Non finicky high grade aluminium.

Side stand mounting lugs for heavy duty side stands

We haven’t a price yet but the cost (airfreight, VAT and import duties takes its toll).

Well do the maths as soon as possible when we’ve checked all the invoices, but these will not be cheap. The profit margin is low until we order in bulk. If these don’t sell that will never happen (do you want to buy 50?)

More accurate details to follow “Specifications”, oh we have 5 rear wheels to fit these too but are “lost” in the post at the moment.
