Hope E-Bike Crankset 165mm Narrow
The Hope E-Bike Crankset 165mm Narrow is a premium e-MTB crankset for riders who want a narrower fit option with a more familiar crank length than 155mm.

Why choose this product

- Narrow offset design helps create a tighter setup where frame and motor clearance allow.
- Designed specifically with modern e-bike riders in mind.
- Self-extracting system makes fitting and removal easier for servicing and upgrades.
- Forged and CNC-machined aluminium construction focuses on long-term durability.
- Made by Hope in the UK for riders who want a premium aftermarket e-bike crankset.
Who it’s for
This crankset is aimed at electric mountain bike riders who want a narrow-offset Hope e-bike crankset in a 165mm length. It suits riders who want a premium replacement or upgrade for a modern e-MTB, especially if they prefer a conventional crank length while still chasing a cleaner narrow-fit setup.
It is most relevant for Brose-based bikes and may also work as a narrow Q-factor option on some Bosch systems if there is enough frame clearance. It is not the right choice if your bike needs a different offset or uses the Bosch Gen 3 BNI spindle interface.
Real-world performance
165mm for a more familiar ride feel
Riders who find 155mm too short often prefer 165mm because it preserves a more natural pedalling feel while still keeping the setup purpose-built for e-bike use. That makes this option especially appealing for riders who want a narrower crank without moving to a very short arm length.
Narrow option for a tighter e-bike setup
The narrow version is aimed at riders looking for a tighter stance where their bike allows it. That can be useful on some Brose systems and selected Bosch bikes, but compatibility and frame clearance need to be checked carefully before buying.
Workshop-friendly fitting
Hope’s self-extracting design adds real day-to-day value. It simplifies installation and removal, which makes this crankset easier to live with for riders who service or upgrade their own bikes.
Premium build quality
This is a genuine upgrade product rather than a basic replacement arm. The forged and CNC-machined aluminium construction gives it the feel of a long-term component choice for riders who want durability and a better-finished e-bike build.
Compatibility and sizing guidance
Check your motor system, frame clearance and spindle interface before buying. The narrow version is most suitable for Brose systems and may also work on some Bosch bikes if there is enough clearance. It is not compatible with Bosch Gen 3 BNI spindle interface.
Choosing the right Hope e-bike crank option| Option | Best for | What to check | When to choose it |
|---|
| 165mm Narrow | Riders wanting a narrower setup with a more familiar crank length | Motor compatibility and frame clearance | When 155mm feels too short but you still want the narrow version |
| 155mm Narrow | Riders prioritising extra clearance in technical terrain | Motor compatibility and frame clearance | When you want shorter cranks and less chance of pedal strikes |
| Standard Offset | Bikes that require the regular Hope e-bike crank offset | Frame and motor fit requirements | When your bike does not suit the narrow version |
| Specialized Offset | Bikes needing the Specialized-specific option | Exact bike and motor fitment | When your e-bike requires the Specialized offset version |
Comparison
165mm vs 155mm
Choose 165mm if you want a more familiar pedalling feel and do not need the extra clearance benefit of a shorter crank. Choose 155mm if your priority is technical riding and reducing the chance of pedal strikes.
Narrow vs standard offset
The narrow option is the right choice only when your bike supports it. If your frame or motor setup needs more clearance, the standard offset version is the safer and more appropriate fit.
Hope vs generic e-bike cranksets
Hope’s value is in its e-bike-specific design, self-extracting system, UK manufacturing and premium finish. This is the option for riders who want a long-term upgrade rather than the lowest-cost replacement.
Is it right for you?
Buy this crankset if you want a premium 165mm narrow e-bike crank and you have confirmed that your bike supports the fit. It is a strong choice for riders who want a more traditional crank length with a cleaner narrow setup.
Do not buy it if your bike needs a different offset, if your spindle interface is not supported, or if you specifically want the shorter feel and extra clearance of a 155mm crank.
Expert insight
For many e-MTB riders, 165mm is the sweet spot between familiarity and modern e-bike function. It preserves a natural pedal feel while still giving the rider a product that is purpose-built for electric mountain bike use rather than adapted from a standard crankset.
