$7,700 — One built. Ready to ride today.

Just pedal. It shifts itself.

No gears to learn. No shift levers. No straining up hills. A Bosch motor gives you the power and an Enviolo automatic hub shifts for you. Set your comfortable pedaling pace once and it stays there — flats, hills, headwinds.

If you (or someone you love) want to ride again without fighting the bike, this is the one.

Nothing on this trike is factory

We started with a bare GreenSpeed Magnum BW frame and built the rest ourselves, here at Laid Back Cycles. The motor, the display, the hub, the wheel, the brakes, the seat, the bars, the tires, the lights — every one of them is a part GreenSpeed does not sell on this trike. It has never been sold or ridden by a customer. There is exactly one.

What we built into it

Part What it does for you
Bosch Performance Line motor, Smart System Hills feel flat. Quiet, smooth, built-in — not a bolt-on kit.
Bosch Purion 200 display One clean screen. Speed, battery, assist level.
Enviolo Trekking heavy-duty hub, custom-laced 26" rear wheel Stepless gearing. No clunk, no chain drop.
Enviolo AUTOMATiQ Shifts itself. You never touch a lever.
TRP hydraulic disc brakes, 180mm rotor Strong, easy stops with light finger pressure.
Schwalbe Pick-Up e-rated tires, 20" front / 26" rear Built for e-bike weight and speed. Flat-resistant.
Extended seat stays + upgraded seat cushion + 1" padded headrest Sit higher and more upright. Easier on your back and neck.
Extended Magnum handlebars + integrated wrist rests Hands relaxed, not gripped.
Grab handle assist bars (pair) Push up and step off with confidence.
NiteRider light set + Hi-Tail extendable rear flag light Traffic sees you, day or night.
Dual mirrors + accessory posts See behind you. Mount what you need.
OR8 chain guide Keeps the chain where it belongs.
GreenSpeed Magnum BW folding aluminum frame, Cross-Over steering 400 lb combined load capacity. Most adjustable frame in its class. Folds.

What it would cost to build this yourself

Over $10,500 in parts at retail, before labor. GreenSpeed's factory Magnum BW e+ is $6,700 and comes with a bolt-on motor, a 20-speed derailleur you shift by hand, and mechanical brakes. This one is $7,700, finished, tuned, and on our floor.

Built for the rider who just wants to ride

This one's for you if shifting gears feels like a chore, if getting on and off a low trike has kept you from riding, or if you want power on the hills without wrestling with technology. Everything on this build works for you automatically: the motor senses your pedaling, the hub shifts itself, and the raised, upright seat with grab handles means you step on and step off with confidence. You don't manage this trike. You just ride it.

Shifts For You

Enviolo AUTOMATiQ shifts automatically as you ride — set your preferred cadence once, then just pedal.

Bosch Smart System Power

The Bosch Performance Line motor delivers smooth, quiet assist that makes hills feel flat and headwinds disappear.

Easy In, Easy Out

Extended seat stays, grab handle assist bars, and an upright riding position make getting on and off simple and confident.
