On Holiday This Week! I'll be back at the shop on Saturday.

Duplex

Custom-built here in Glasgow, the Duplex tandem tricycle is perfect for stable, fast touring with two people. Built entirely out of aerospace-grade seamless 4130 steel, fillet-brazed, it has S&S frame separators as standard to make it much easier to store and transport.

Because it is built to order, anything is possible, but the “standard” specification shown here is a good mix – three chainrings and a 3×9 rear wheel to give 81 gears in a very wide spread, twin hydraulic front disc brakes, a rear disc brake with parking lock, mudguards and carrier.

Duplex Tandem Tricycle – prices start at £5995 depending on specification.

Delivery time is around 4 months at present.

  1. Could the Duplex tandem trike be equipped with electric assistance? I was thinking of a Bafang bottom bracket kit but this wouldn’t be suitable for the front as shown (left side chainring) and it looks like the rear would obstruct the motor. Could a rear wheel drive work?

    1. Yes, a rear hub motor like a Heinzmann would work, in combination with a rear derailleur – no hub gears of course.

    1. Theoretically yes, but I’m not sure how stable that would be – the high stoker would be very far back from the centre of stability, so it might be prone to tipping over in corners. And of course it wouldn’t be like a Pino, the stoker would be much higher up than the pilot.

      1. Happy for stoker to be higher than pilot, they’ll get a view! My thinking is that the tadpole configuration might reduce the risk of tipping.

  2. This tandem looks very fine, i like the fillet brazed frame. Can you please explain the length adjustment for the stokers seat position ? Thank you.

  3. Pros and Cons of having the new Duplex built w/ IPS, Captain controls all vs the ICE/Trice Explorer Tandem Trike for sale and doing the same to it? In the States. For son w/ autism and I to ride. Thanks. Feel free to PM.

  4. I have a good friend thats been looking for someone that would build him a fully suspended tandem trike – is that something you would consider?

    Thankyou!
