Dreadnought E
Dreadnought E is a carbon, mixed-wheel eMTB with 180/170 mm travel. Tier 1 and Tier 2 use M2S; Tier 3 and Tier 4 use M2. Each tier has separate 600 Wh and 800 Wh records. Geometry preserves the original S1–S4 sizing and signed BB-drop convention. M2 Boost torque is omitted because the same page gives conflicting 120/125 Nm figures.

Geometry by size
Manufacturer Dreadnought E chart for a 180 mm fork (596 mm axle-to-crown), MX wheels and original S1–S4 sizes. The manufacturer publishes BB drop as -20 mm; the sign is preserved, not normalized to another brand's convention.

Both layers use the same transparent reference artwork, aligned at the bottom bracket. Each is scaled horizontally by its published reach and vertically by its stack. This illustrates reach and stack differences only: wheelbase, angles, wheels and frame shapes are not reconstructed. Use the documented values and deltas below for all other measurements. This is not a fit prediction.

Manufacturer height guide
No manufacturer height range is recorded for this size.
Height guidance is a starting point. Rider proportions, setup and preferences also matter; this is not a fit guarantee.
Price observations
No sourced price observation is recorded for this build.
Prices are in euros for the stated build, market and date. A conversion is an estimate, not a local retail price. Historical observations are not current offers. Confirm taxes, fees and final price with the seller.
Availability
Current stock and delivery availability are not verified. Check with the manufacturer.
Intended use and assessment
Enduro
No sourced strengths or trade-off assessment is recorded. Specifications alone do not establish how a bike will ride.
