A replacement rim for downhill e-bikes designed for durability and reliable wheel builds. Riders tackling rocky, technical trails will gain greater confidence with a tough, serviceable wheel component. Does hammer-ebikes Bike Rim make a sensible upgrade for serious trail riders?

⚡ At a Glance
  • Rim Strength: Double wall construction suited to heavy impact and repeated stress
  • Best for: Downhill e-bike riders who need robust wheel builds for rough terrain
  • Not ideal for: Lightweight cross-country riders prioritising minimal rotational mass

Double wall construction increases stiffness and impact resistance. Thirty six spoke count supports stronger wheel builds for heavy-duty use.


Robust impact resistance - with double wall construction

Double wall construction means two joined rim walls that raise lateral and radial stiffness and help resist denting under hard impacts. The joined walls also distribute load across the rim profile more evenly during heavy hits.

Greater resistance to knocks and rim deformation on rocky descents. Fewer service visits expected when riding demanding trails regularly.

Stronger wheel builds - with a 36-hole spoke pattern

A 36-hole rim allows for a denser spoke pattern that spreads forces across more spokes and creates a stiffer, more durable wheel build when laced correctly. Higher spoke counts are commonly used for heavy-duty and e-bike applications.

Wheel builders can produce a resilient wheel suited to heavier loads and aggressive braking. Suitable for riders who need reliable wheels under frequent stress.

Trail-friendly handling - with 27.5-inch diameter

The 27.5-inch diameter offers a balance between manoeuvrability and rollover capability, favouring quicker direction changes while still smoothing medium-sized obstacles. Wheel diameter influences geometry and handling characteristics.

Nimble handling in tight, technical sections while maintaining adequate rollover on rough ground. A practical choice for riders favouring responsiveness on steep trails.
