Just pedal. It handles the rest.
No gears to learn. No shifting. No straining up hills. This trike has a Bosch motor for power and an Enviolo automatic hub that shifts itself. You set your comfortable pedaling pace once, and it stays there — on flats, on hills, into headwinds.
If you (or someone you love) want to ride again without fighting the bike, this is the one.
Built for comfort and confidence
- Sit upright and relaxed — extended handlebars and seat stays take the strain off your neck, shoulders, and back
- Get on and off easily — grab handle assist bars and a higher seat position

- Dual mirrors so you always see what's behind you

Why this build instead of a stock electric Magnum?
GreenSpeed's factory Magnum BW e+ is $6,700. For $2,000 more you get a Bosch motor instead of a bolt-on kit, automatic shifting instead of a 20-speed derailleur, hydraulic brakes instead of mechanical, and every comfort upgrade listed above — over $3,800 in parts. We built it here at Laid Back Cycles. There's only one.

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.
