The Shimano STEPS BT-E8014 is a high-capacity 418Wh down tube battery purpose-built for the Shimano E-8000 STEPS e-bike system. Engineered specifically for mountain bike use, it delivers confident power delivery across demanding terrain while keeping a low profile to preserve natural bike handling.

Highlights

  • 418Wh capacity: 36V, 11.6Ah power reserve capable of exceeding 100 km range in normal mode, keeping you riding longer between charges.
  • MTB-dedicated design: Low-profile form factor sits flush along the down tube, preserving handling balance and ground clearance on technical trails.
  • Impact and vibration resistant: Built to handle the rigours of mountain biking — rugged construction absorbs trail punishment without compromising cell integrity.
  • Waterproof construction: Sealed against ingress so you can ride confidently in wet conditions without worrying about battery exposure.
  • 1,000-cycle longevity: After 1,000 full charge cycles the battery retains more than 60% of its original capacity (300Wh+), giving years of reliable service.
  • Integrated charge display: On-board LED charge level indicator with error signal info lets you check battery status at a glance.
  • Secure lock system: Lockable mount keeps the battery secure off-bike for safe storage and theft deterrence.
