Rides Like a Full-Size Bike
Unlike many folding eBikes, the Vektron never feels compromised on the road. Its stiff aluminium frame and carefully tuned geometry deliver stable, confidence-inspiring handling at speed and in traffic.
The powerful Bosch Performance motor provides smooth, natural assistance up to 340% support, making hills, headwinds and loaded commuting feel effortless.
Whether you’re weaving through central London or cruising home after work, the P5i rides with the assurance of a much larger bike.
Designed for Real-World Carrying
The integrated Atlas V rear rack supports loads up to 27 kg and features a dual-rail design compatible with:
- KLICKfix
- Racktime SNAPIT 2.0
- Ortlieb Quick-Lock 2.1 & 2.2
It accepts panniers, baskets and child seats, and also doubles as a stable parking stand when folded — a small detail that makes a big difference day to day.
Safety, Certification & Aftercare
Every Vektron P5i is independently tested and certified to meet:
- EN 15194 eBike standards
- UL 2849 electrical and fire safety certification
With Bosch supplying the full drive system and battery, reliability is proven at scale.
Tern offers a 10-year limited warranty when registered via Tern Care, with guaranteed parts availability for at least seven years.
And with Fully Charged’s Bosch-trained mechanics, you’ll always have expert support, servicing and advice available.
