The Schwalbe Magic Mary Radial Gravity Pro Ultra Soft was fitted to the front of our Amflow test bike, which impressed us with its grip and confident changes of direction. For riders who put confidence on technical trails ahead of minimum weight or rolling drag, it is a compelling starting point.
This review covers the photographed 29 x 2.5in version, combining our Amflow riding impressions with Schwalbe’s construction information. The radial casing is the interesting part beneath the familiar tread, but compound, casing and pressure all matter. Here is how it fits into an eMTB setup, and how the exact version compares with alternatives from Maxxis and Continental.
Schwalbe Magic Mary Gravity Pro Radial Ultra Soft – 29 x 2.5

Our verdict
A convincing front-tyre option for riders who value grip and control on technical trails. Our riding impressions come from the complete Amflow test bike: the Magic Mary was part of a confident front end, but we have not isolated its contribution with a tyre swap. The exact version matters. This card covers the 29 x 2.5 Gravity Pro Radial with ADDIX Ultra Soft rubber, not the Soft compound. Its listed 1,340g weight and traction-led construction make it a considered choice for demanding riding rather than an automatic upgrade for every eMTB. Pressure setup remains important.

Construction: what the radial casing changes
A tyre’s casing is the fabric structure beneath the rubber. Schwalbe changes the angle of its threads so the casing can deform more locally around obstacles. The aim is to let the tyre wrap around uneven ground without disturbing as much of the surrounding structure.
Schwalbe claims around 30% more contact area at equal pressure. That is its own design comparison, not a promise of 30% more grip. Surface, load, rubber and pressure still influence traction. This construction is also different from a fully radial automotive tyre.
Our tyre’s sidewall identifies Gravity Pro, Radial and Ultra Soft. Those details are essential when shopping: a Magic Mary with a different compound or casing is not the same product. The linked UK retailer lists this 29 x 2.5in version at 1,340g. That is a quoted specification, not a weight measured on our scales, and should not be applied to every Magic Mary.
On the trail: our Amflow riding impressions
In our Amflow PX Carbon Pro review, the bike gripped well and changed direction confidently. The Fox 36 fork also stood out for its support through corners. The Magic Mary formed part of that reassuring front end, and the overall impression gives us good reason to consider it for a grip-focused build.
This was a complete-bike test. We have not swapped tyres on the same bike to isolate the radial casing or Ultra Soft compound, so we cannot claim a measured improvement over a conventional Magic Mary, Assegai or Kryptotal. Likewise, this test does not establish a long-term wear rate, puncture advantage or battery-range penalty. The useful finding is the confidence of the Amflow package with this tyre fitted.
Pressure and tubeless setup
Schwalbe recommends starting with the pressure used in a comparable conventional casing, then adjusting to suit conditions. Radial construction is not an instruction to automatically remove several psi. Your starting point still needs to suit rider weight, rim width, speed, terrain and which wheel carries the tyre.
Use a gauge and make small changes on a familiar section of trail. Look for support under braking and cornering as well as comfort over rough ground. If the tyre feels unstable or you strike the rim, address the setup before pushing harder. Follow the limits on your actual tyre and rim; specifications and versions can change.
For a tubeless setup, check tyre and rim compatibility, bead seating and sealant condition. Our eMTB tubeless sealant guide covers formulas and maintenance. Sealant cannot correct an unsuitable pressure or damaged bead.
Where it makes sense on an eMTB
The front wheel is where we would prioritise this version. Steering confidence matters on technical descents, and that is a clearer reason to choose it than simply wanting the newest casing. Riders who mostly use smooth tracks or long road links should give rolling efficiency and weight more consideration.
Schwalbe acknowledges that the increased contact area can add rolling resistance. A motor helps with climbing effort, but extra drag still requires energy. We have not measured the size of that effect on our bike, so there is no defensible percentage range penalty to quote. A front-only change also lets you retain a rear tyre chosen for the rest of your riding.
Value for money and alternatives
The exact Magic Mary Gravity Pro Radial Ultra Soft 29 x 2.5in was £68.99 at Tredz when checked on 28 October 2026, against a listed £83.99 RRP. The alternatives below were also listed in stock in the specified sizes. These are tyre-only prices; delivery is excluded from the comparison and prices can change.
Compare the whole specification before chasing a discount. A lighter casing or a different compound can explain a lower price, and a tyre carrying the same tread name may have a different purpose. The two competitors below are researched alternatives, rather than tyres tested head-to-head for this review.
Maxxis Assegai 3C MaxxGrip DoubleDown
The 29 x 2.5 WT Assegai in 3C MaxxGrip and DoubleDown was £59.95, £9.04 less than the reviewed Magic Mary. It is the closer alternative in intent: a grip-focused front tyre with a reinforced casing. Maxxis lists DoubleDown with two 120 TPI layers, while the WT profile requires an appropriate rim width. Choose it for that specification and price, rather than assuming it is interchangeable with the cheaper MaxxTerra EXO+ version.
Maxxis Assegai 3C MaxxGrip DoubleDown – 29 x 2.5 WT
A front-tyre alternative for demanding trails, combining Maxxis’s grip-focused compound with a reinforced DoubleDown casing. Researched comparison, not a back-to-back test.
At Tredz
Assegai 29 x 2.50 WT, 3C MaxxGrip, DoubleDown, 120 TPI, folding TR, black
+ Pros
- 3C MaxxGrip compound targets demanding traction
- DoubleDown uses two 120 TPI casing layers and a butyl insert
- Relevant front-tyre alternative for enduro and eMTB riding
− Cons
- Grip-focused construction is not aimed at minimum drag
- WT profile needs appropriate rim width
- Not ridden back-to-back with the Magic Mary in this review

Why it makes the shortlist
The Assegai is the closest of these alternatives in intent: a front tyre for riders who put traction ahead of easy rolling. This exact version combines 3C MaxxGrip rubber with DoubleDown construction, so a cheaper EXO+ MaxxTerra listing is not a like-for-like price comparison. Maxxis recommends the Assegai for front use, and the WT profile is intended for suitably wide rims. At the checked price it costs less than the reviewed Magic Mary, making it worth comparing before buying. That is a specification and price comparison; we have not established a grip, damping or durability winner in a controlled test.

Continental Kryptotal Fr Enduro Soft
The 29 x 2.4 Kryptotal Fr Enduro Soft was £66.99, just £2 less than the Magic Mary. Its front-specific mixed-terrain tread and Enduro casing make it relevant to technical trail riding, while Continental’s Soft compound offers a different grip-and-rolling balance from its SuperSoft option. It is worth considering for varied trail days, but its narrower nominal size and different rubber mean this is not an identical specification. We have not measured an efficiency advantage over the Schwalbe.
Continental Kryptotal Fr Enduro Soft – 29 x 2.4
A front-specific mixed-terrain alternative with an Enduro casing and Soft compound, for riders comparing grip with rolling efficiency. Researched recommendation.
At Tredz
Kryptotal Fr, Enduro casing, Soft compound, folding tubeless ready, black/black, 29 x 2.4
+ Pros
- Front-specific tread for mixed terrain
- Enduro casing with Apex reinforcement
- Soft compound offers a different balance from maximum-grip options
− Cons
- Narrower nominal size than the reviewed 2.5in Magic Mary
- Soft compound is distinct from Continental’s SuperSoft option
- No direct same-bike comparison in this review

Why it makes the shortlist
The Kryptotal Fr Enduro Soft is a useful alternative if your riding combines technical descents with longer trail days. Continental positions its Soft compound as a balance of grip and rolling behaviour; that makes this a different proposition from simply choosing the tackiest available rubber. The front-specific tread and reinforced Enduro casing keep it relevant to demanding eMTB use. Check the name carefully: Trail Endurance, Enduro Soft and Enduro SuperSoft are separate versions. The checked 29 x 2.4 Enduro Soft costs slightly less than the reviewed Magic Mary. We have not tested the two back-to-back or measured an efficiency advantage.

Verdict
The Magic Mary Gravity Pro Radial Ultra Soft makes most sense as a front tyre for technical MTB and eMTB riding, where grip and control take priority. It contributed to a confident Amflow test bike, although that complete-bike experience does not prove that the radial version outperforms every conventional alternative.
At £68.99, it deserves a place on a grip-focused shortlist. The compromises are its substantial listed weight, the potential rolling-resistance cost and the need to get pressure right. Buy the precise casing and compound you want, and treat it as a deliberate choice for your trails rather than an automatic upgrade for every ride.
Frequently asked questions
Is every Schwalbe Magic Mary a radial tyre?
No. Magic Mary is the tread family, and conventional versions also exist. Check for Radial, the casing designation, compound and exact size before ordering. This review concerns the Gravity Pro Radial Ultra Soft 29 x 2.5in version.
Would you fit this Magic Mary to the front or rear?
Our test tyre was fitted to the front, and that is where we would prioritise it for technical riding. A rear-wheel choice should also account for rolling efficiency, wear and impact demands. This review does not assess a matching pair.
What pressure should I run in the radial version?
Start from an appropriate pressure for a comparable conventional casing, as Schwalbe recommends, then adjust in small steps. There is no single pressure for every rider and rim. Stay within the limits of both components and check support as well as comfort.
Does Gravity Pro make it puncture proof?
No. Cut protection, resistance to rim impacts and retention of air at the bead are different issues. Gravity Pro does not guarantee survival of every impact, and our complete-bike riding impressions do not establish a puncture-resistance advantage.
