Elite's pitch for the Rivo is simple: a direct drive smart trainer that weighs 10kg, folds up, carries by a handle and still runs Zwift virtual shifting. Nothing else in the category is this easy to move. The version on sale in the UK arrives with the Zwift Cog and Click already fitted, so you skip the cassette shopping entirely, and it sits around £469 on Amazon, which is roughly what a Wahoo KICKR Core 2 costs.
That comparison is where the review gets complicated, because independent testing has found real problems with the Rivo's power numbers under hard efforts, and its main rival at the same price does not have them. What follows is an attempt to be straight about both sides: this trainer solves a genuine problem for people short on space, and it is not the one to buy if your training runs on precise wattage.
How we review
This review is based on Elite's published specifications, sustained testing from established UK and US cycling test outlets, and the pattern of verified owner feedback. We have not run this exact unit through a full winter block, so we report findings that repeat across independent tests, including the accuracy criticism, rather than a single reviewer's impression.
Flat dwellers, people training in a shared room, and anyone who has to put the trainer away after every session. At 10kg with a carrying handle and folding legs, the Rivo can live in a cupboard and come out in under a minute, which is a completely different experience from wrestling a 20kg trainer out from behind a sofa. The unplugged resistance mode extends that further, because you can warm up in a race car park with no power source.
It also suits riders whose training is mostly steady endurance and structured intervals below sprint intensity. Aerobic fitness responds well to consistent structured sessions, and survey work on indoor cyclists found functional threshold power positively associated with the frequency of structured workouts and races, and negatively with unstructured riding. The Rivo handles that kind of work perfectly well.
Who should look elsewhere: racers on Zwift, anyone chasing a power PB, and riders who want the trainer to feel like the road. More on all three below.
Check the Elite Rivo price on AmazonAssembly is one Allen key and about ten minutes: bolt on the legs, fit the right axle adaptor, plug it in. Elite includes adaptors for quick release 5x130 and 135 and 12x142 thru axle, which covers nearly every road and gravel bike sold in the last decade. The instructions are adequate rather than good, and lack the colour coding that makes rival trainers idiot proof at 10pm on a Sunday.
The physical design is the reason to want one. Legs fold flat, the handle sits where your hand naturally goes, and 10kg is light enough to carry up a flight of stairs without planning the manoeuvre. Compare that with the Elite Avanti, which is a better trainer in almost every measurable way and a considerably worse one to move.

The flywheel is the compromise that pays for the low weight. Elite lists it at 4kg, which is roughly half what you find in heavier direct drive trainers, and you feel that at both ends of a pedal stroke. Momentum runs out faster, the sensation is choppier than the road, and the steps between virtual gears on the Zwift Click land with more of a thump than they should, especially at higher resistance. It is not unpleasant, and after a fortnight you stop noticing. But nobody who has ridden a heavy flywheel trainer will call this realistic.
Light also means mobile. Stand up and sprint and the whole unit shifts under you, which is fine for a 20 second effort and distracting during a Zwift race finish. A mat helps a little.
Noise is a genuine strength. Testers measured about 60 to 62 dB at steady moderate power and 65 to 66 dB sprinting, and the Zwift Cog keeps drivetrain rattle down because the chain sits in one fixed line. That is quiet enough for a 6am session in a flat with thin walls.
Here is the problem. Elite claims ±2.5% and at endurance and tempo wattages the Rivo lands inside that. Push into sprints and it under-reports, sometimes substantially, and reviewers also recorded power drift over the course of a ride. There is no auto calibration to catch this, and running a manual spindown means switching between connection types, which is exactly the kind of faff that means nobody does it.
For most home training that matters less than it sounds. If your sessions are zone 2, sweet spot and threshold intervals, and you compare your numbers only against your own previous numbers, consistent under-reading is a nuisance rather than a disaster. If you race on Zwift, chase power records or train to a coach's file, it is disqualifying, and you should spend the same money on a Wahoo KICKR Core 2 instead.
Connectivity has its own sharp edges. Virtual shifting runs over Bluetooth only, while Zwift's Race Mode wants a WiFi connection, so you can end up choosing between two features that should coexist. WiFi itself is limited to 2.4GHz. And the total absence of ANT+ will catch out anyone planning to record power on a Garmin head unit.
At £469 the Rivo is not cheap enough to forgive the accuracy issues, because the KICKR Core 2 sits at roughly the same UK price with better data and a more convincing ride. What the Rivo has that nothing else at this money offers is portability: 10kg, folding legs, a handle and a mode that works without mains power. If you live somewhere the trainer has to disappear between sessions, that is worth real money and might well be worth more to you than the last 20 watts of sprint accuracy.
If you would rather have the accuracy and can stretch, the Elite Avanti is the better trainer from the same brand, and the Tacx NEO 3M is the premium end of the same idea. Riders who want a self contained machine instead of a trainer plus bike should read our best smart exercise bike UK guide, and everything in this category sits in our best turbo trainer UK roundup.
See today's Elite Rivo priceElite claims ±2.5%, and at steady endurance wattages independent testing broadly backs that up. The problem is sprints and long rides: reviewers found the Rivo under-reporting during hard efforts and drifting mid-session, and there is no automatic calibration to correct it. For zone 2 and threshold work it is fine. For racing where every watt counts, it is not the trainer to buy.
It ships with a power supply and needs it for full resistance control, but there is an unplugged mode that gives you usable resistance without a socket. That makes it one of the few direct drive trainers you can genuinely take to a race car park or a garage without power.
No. Connectivity is Bluetooth (dual channel) and 2.4GHz WiFi, plus the Zwift BLE protocol. If your head unit or older app relies on ANT+ FE-C, check before you buy, because this is the single most common complaint about the Rivo's spec sheet.
The freehub takes Shimano and SRAM 9, 10 and 11 speed, Shimano 12 speed road, and SRAM SX and NX 12 speed. The version reviewed here comes with the Zwift Cog already fitted, so you can run any bike from 8 to 12 speed without matching a cassette.
Around 60 to 62 decibels at steady moderate efforts and 65 to 66 when sprinting, measured by independent testers. That is quiet enough for a flat or a garage next to a bedroom, and most of what you hear is drivetrain rather than trainer.
The KICKR Core 2 sells for roughly the same money in the UK and gives you better power data, a heavier flywheel and a more solid ride feel. Buy the Rivo if portability, folding storage and the unplugged mode matter more to you than the last few watts of accuracy. Otherwise the Wahoo is the safer purchase.
