Kazim is a UK-based cyclist and writer who discovered his passion for riding during lockdown six years ago and hasn’t looked back since. He now rides around 100 miles a week, exploring road and light gravel routes from his base in the Cotswolds, a cycling paradise. When he’s not riding or writing about e-Bike trails in the US, he’s exploring cafés, cooking, and keeping busy as a soccer dad.

Cannondale topstone e-bike

Cannondale has built the Topstone’s reputation as a fast and versatile gravel bike that performs well on roads, rough lanes and light gravel. The Topstone sits at the faster end of the gravel spectrum. It can hold its own on the road while offering the wider tires, stability and durability needed for mixed-surface riding.


The Topstone Neo adds Bosch electric assistance, creating a premium electric gravel bike capable of tackling steep hills, long rides and fast weekend adventures.


In this Cannondale Topstone Neo review, I look at its motor performance, battery range, gravel capability, tire clearance, comfort and who I think will get the most from this premium electric gravel bike.

What is the Cannondale Topstone Neo?

The Cannondale Topstone Neo is a premium electric gravel bike based on Cannondale’s conventional Topstone gravel bike platform. This is a bike that I have ridden alongside, and ridden myself at various points, on both short and long road rides and light gravel. In practice, the Cannondale Topstone Neo is what I would regard as a fast gravel bike. It can hold its own on the road while also feeling stable and performing well on light gravel.

In my neck of the woods, and even though they are not necessarily marketed this way, fast gravel bikes such as the Topstone are increasingly being used as winter bikes. Their wider tires and more robust frames can cope with potholes, muddy roads, big puddles and poor surfaces, extending the riding season into the colder months.

Key Specifications

  • Frame: SmartForm C1/C2 Alloy or BallisTec Carbon, depending on model
  • Fork: Full carbon fork or Lefty Oliver 30 mm suspension fork on Lefty models
  • Motor: Bosch Performance Line CX or Bosch Performance Line Speed 250 W mid-drive motor, depending on model and market
  • Motor torque: Up to 85 Nm
  • Maximum assistance: Up to 28 mph on US Class 3 models; 15.5 mph in UK and EU versions
  • Battery: Bosch PowerTube 500 Wh integrated battery
  • Estimated range: Up to approximately 125 km or 78 miles on most models
  • Tire clearance: Up to 700 × 42 mm on alloy models or 650b × 47 mm / 700c × 37 mm on carbon models, depending on frame and wheel configuration
  • Drivetrain: Shimano GRX 1x11, 2x10 or 2x11, depending on model
  • Brakes: Shimano GRX hydraulic disc brakes
  • Weight: Approximately 17.5–20 kg, depending on frame material, size and specification
  • Mounts: Multiple bottle cage, rack and mudguard mounts for commuting, bikepacking and touring
  • Wheel size: 700c or 650b, depending on model

What motor does the Cannondale Topstone Neo have?


Both the alloy and carbon models are powered by Bosch motors, delivering up to 250 W of continuous motor assistance and as much as 85 Nm of torque. US Class 3 versions can provide assistance up to 28 mph, so you should be able to cover ground quickly on this machine.

With its sporty e-Bike frame weighing between approximately 17.5 and 20 kg, depending on the model, frame size and specification, the Cannondale Topstone Neo has enough motor power to deliver punchy performance on gravel trails and steep inclines.

The 85 Nm of torque is a serious amount of assistance for a bike this light. It should make steep gravel climbs, loose inclines and longer road ascents much easier, particularly when carrying bikepacking luggage

Tire clearance and comfort


I have said before that, for all-day or multi-day gravel riding, I would want a minimum of around 45 mm tire clearance for comfort, traction and stability.

If 45–50 mm tires are good enough for the younger, fitter and more robust riders taking on events such as Unbound, then 45 mm clearance is certainly good enough for me.

The alloy model offers up to 42 mm clearance. Combined with the stiffer aluminum frame, I think that could result in a fair amount of bone-shaking, sore wrists and a sore posterior on longer and rougher gravel rides.
The carbon model offers greater natural vibration absorption and can accommodate up to 47 mm tires with the appropriate 650b wheel configuration. That is the version I would choose if I intended to use the Cannondale Topstone Neo for long-distance gravel riding.

The 700c carbon configuration with 37 mm tires would feel quicker on roads and smoother gravel, but it would not be my preferred option for long days over rough surfaces.

Cannondale Topstone Neo battery range


The integrated Bosch 500 Wh battery provides an impressive estimated battery range of up to 78 miles. What I particularly like is Bosch’s intelligent range estimator, which continuously updates your remaining range based on battery level, assistance mode, rider weight, terrain and speed.

Being relatively light, particularly in its carbon form, the range can potentially be extended towards 90 or even 95 miles by a fit performance rider using Eco mode and relying more heavily on pedal power. I have witnessed it. This matters because, let’s face it, you need some battery capacity left for scheduled and unscheduled exploration—or, more simply, getting lost—which is fairly common on gravel rides.

What about the Lefty Oliver suspension fork?


Cannondale also offers the distinctive Lefty Oliver suspension fork. It does look a little strange. It is essentially a one-sided suspension fork that can make it appear as though the right side of the fork has snapped off.

It has been designed to provide damping and additional comfort while preserving speed. On paper, it should make long-distance gravel bike riding more comfortable, particularly over repeated bumps and rough tracks.

However, it may puzzle unfamiliar mechanics, cost more to service or replace, and become the butt of the occasional joke. I would also wonder whether such an unusual and hi-tech component could affect resale value, particularly among buyers who prefer simpler, more conventional equipment. Personally, I would leave the Lefty Oliver to the early adopters—of which there are plenty—and choose the conventional carbon fork.

Who is the Cannondale Topstone Neo designed for?


The Cannondale Topstone Neo is primarily aimed at:

  • Medium to long-distance recreational riders (choose the Carbon 47 mm for long distance)
  • Weekend gravel cyclists
  • Performance-focused riders

The on-site marketing pitches it as a weekend gravel fun machine. It is aimed more at performance than relaxed leisure riding and will appeal to cyclists who may often ride alongside people on conventional road or gravel bikes. That is why it needs to look sporty and discreet rather than like a bulky electric bike. It achieves this well.

Frequently Asked Questions

Does the Cannondale Topstone Neo justify its premium price?

For the right rider, yes. The Cannondale Topstone Neo combines a high-quality gravel platform with powerful Bosch assistance, hydraulic disc brakes, Shimano GRX components and a relatively lightweight frame. It is also unusually versatile. It can work as a fast gravel bike, long-distance road bike, winter bike, commuter and light bikepacking machine.

However, buyers need to choose the correct version carefully. A road-focused rider may prefer the faster 700c setup, while someone planning longer and rougher gravel adventures would benefit from the carbon frame and wider 650b tyres.

As a premium bike, the Topstone Neo is pricey when purchased new. However, used and professionally refurbished models can offer much better value, particularly as more examples begin appearing on the second-hand market.

Is the Cannondale Topstone Neo a good winter bike?

Although Cannondale has not strongly pitched it this way, the 37 mm and 42 mm tyre-clearance versions look like excellent winter bikes to me.

Many riders I know switch to fast gravel bikes during autumn and winter for road riding because they cope better with potholes, muddy lanes, wet leaves, icy roads, greenways and riverside trails.
Where I live, gravel bikes can struggle on genuine off-road routes during winter. The ground becomes so wet, muddy and slippery that all but the most skilled off-road riders switch to full mountain bikes or stay on the road.

In those conditions, the Topstone Neo makes a lot of sense as a fast winter road and mixed-surface bike.

Is the Cannondale Topstone Neo a Class 3 e-Bike?

The Topstone Neo is a Class 3 e-Bike and provides pedal assistance up to 28 mph. Specifications vary by model and market, so buyers should check the exact version before purchasing.

Key Takeaways


  1. The Cannondale Topstone Neo is a premium electric gravel bike based on Cannondale’s fast and versatile Topstone platform.
