KTM Macina Race SX 20

The KTM Macina Race SX 20 is a hardcore hardtail boasting great performance.

It is an agile, lightweight 29er featuring a great spec. As well as high quality components, it features the new, powerful SX 55Nm motor from Bosch. Total bike weight is amazingly light at just 20.2kg (excluding pedals).

Bosch SX Motor

When muscle power and electric support work in conjunction, you get top performance exactly when you need it. Also, Bosch’s Performance Line SX is a sporty drive unit that is lighter and more compact than all their other drives.

600Watts of power
only 2kg in weight
max 55Nm torque
sprint mode for sporty riding

Pedal faster, pick up speed even faster: The Performance Line SX works at least as hard as you do. It has a reduced pedal resistance of more than 50 percent compared to the Performance Line CX, a narrower design of the cranks and an almost silent motor.

At around just 2kg, the Performance Line SX is Bosch’s lightest drive with the highest power density. Likewise, it reduces the total weight of your eBike, delivers greater agility and is ideal for fans of a sporty riding style. In addition, the compact drive unit disappears elegantly into the crank area so it looks like a conventional bike.

The KTM Macina Race SX 20 Features the Latest Bosch Technology

Bosch’s new SMART SYSTEM features on the Macina Race SX, with a PURION 200 display on the left of the bars. It provides access to all power levels at the push of a button. It’s colour background is easy to read. Also, it displays the charge status of the battery and other metrics.

High Quality Components

A nice set of Suntour X1 32 Air forks on the front of the Race SX ensure a hugely dynamic and responsive ride at all times.

Furthermore, a nice combination of Shimano MT201 / MT200 2-piston brakes tame the bike when required and act responsively and effectively. Gearing is via the new Shimano CUES system for durability, with a smooth changing 9-speed derailleur and wide range 11-46T cassette.

A set of Schwalbe Smart Sam Performance tyres ensure low rolling resistance and optimise treadwear and traction.

KTM Macina Race SX 20 has a Removeable Battery

Unlike other brands of eMTB offering the new SX motor, the full range of KTM Macina eBikes have a removeable battery.

The Bosch CompactTube 400Wh battery integrates seamlessly within the frame producing a bike that’s barely recognisable as an ebike.

The KTM Macina Race SX 20 is a rock solid hardtail with great agility, power and performance thanks to the new Bosch SX motor and lightweight nature.

How do I measure my height?

With your shoes off, stand upright against a wall, with your shoulders back and legs together. Use a pencil to make a small mark on the wall above your head (make sure you hold the pencil parallel to the floor). Then measure from the floor to your mark, in centimetres or feet and inches.

How do I measure my inside leg length?

With your shoes off, stand upright with your back against a wall. Place a book/ruler between your legs, level with your crotch. Then measure from the floor to the top of the book/ruler, in centimetres or feet and inches (it’s easier if a friend helps).

Q & A

Do all brands of ebike use the same unit of measurement?

No. Most brands show sizing in centimetres, however some use a S/M/L system, and others use inches. The table above includes all of these variations to help you find the right size.

Which size should I go for if I'm in between those listed?

If your measurements suggest that you have a choice of two different sizes, then in the end it’s a personal choice. Here are some rules of thumb to consider: Touring/Trekking ebikes - choose the smaller size. It is possible to make a smaller frame bigger (for example, by raising the saddle or fitting a longer the stem), whereas if the frame itself is too big for you, it’s likely to be less comfortable and won't feel right. eMTBs - choose the larger size. You’ll find an eMTB with a slightly larger frame easier to handle than one that feels cramped. You can always fit a shorter stem if necessary to reduce the reach to the handlebars.

How are ebike frame sizes measured?

An electric bike’s frame size is calculated by measuring the distance from the top of the seat tube (where the seat post inserts), to the centre of the front chainring. Sizing Guide
