Rondo has announced the release of its new Bogan ST, a fully redesigned off-road bike with an all-new steel frame, aimed at bikepackers.

The 2025 Bogan ST sports traditional tube profiles made from steel, a progressive geometry and a feature-filled design. It's available for £2,899.

Alongside unveiling the Bogan, Rondo has confirmed full spec and pricing details for its IOON electric gravel bike, which scooped a Design and Innovation award when it was announced in January.

The Fazua mid-motor powered IOON follows in the footsteps of bikes such as the highly capable Mylc and soft-tailed RUUT.

The new 2025 Bogan has been redesigned from the ground up.

The all-new steel frame comes with geometry that Rondo says has been optimised to keep a fully laden bike more stable on rough terrain.

The slackened front end features a longer fork, making the Bogan suspension-ready.

The tyre clearance is larger than the previous iteration, at 29x2.1in, or 27.5 with 2.6in tyres.

The down tube has external routing braze-ons, along with multi-bottle mounts and bars to strap a tool roll to easily.

The back end is SRAM Universal Derailleur Hanger and full-mount compatible.

The Bogan ST is priced at £2,899 with SRAM Apex hydraulic brakes, X1 1x12 drivetrain and WTB Sport Terra wheels.


Rondo goes electric with the IOON

The IOON electric gravel bike made headlines earlier in the year when it won a Design and Innovation award.

The frameset, which bears plenty of resemblance to the pedal-powered Rondo RUUT, houses a Fazua Ride 60 drive system comprising a removable down-tube battery and a mid-mount motor.

The IOON CF1 comes with a SRAM Force drivetrain (although not necessarily the same Force drivetrain as this pre-production sample), DT Swiss HGC 1400 gravel wheels, a Fazua Ride 60 powertrain with a new 430Wh battery and a new Rondo ICF cockpit, including a new forged carbon stem.

The CF1 is priced at £8,999, while Rondo is also offering a CF2 model with SRAM Apex AXS, Rondo wheels and the same powertrain for £6,199.

For those who prefer their gravel bikes to be of the flat-bar persuasion, there’s the IOON CFU with SRAM Apex AXS, DT Swiss HG1800 wheels and 50c Vittoria Terrino Max tyres for £5,999.
