Body Sculpture TRIM BIKE

Product Information

I had to read the included instructions carefully to find out how to operate the unit, which might seem an odd complaint but is a little disappointing in an age of intuitive tech. With its anodised aluminium frame and curved Gorilla Glass display, it’s a slimmer and more modernist design than we’re used to with cycling-specific GPS computers.

Re-uploading the indoor ride also appears to have fixed the appearance of power drops in that ride too. Simon Bromley / Immediate Media At 55 x 94 x 12.5mm, it’s similar in size to a Garmin Edge 810 , (albeit a little slimmer) and weighs 63g. The design of the machine is pretty standard, with the resistance knob on the front and the display above. But, there is also a handle for transportation.With no option to delay or cancel the update, it can be quite frustrating if you’re in a hurry to get out of the door, onto the bike and dropping watt bombs. The app also stalled a few times during updates. This led to a confusing few minutes of me trying to reset the One, before I worked out that I needed to reset the smartphone app, then reconnect my phone to the One to restart the firmware update. Rides can be viewed in the app or uploaded directly to Strava , but this has to be done manually for each ride – the app doesn’t sync to Strava automatically. As we’ve already noted, the Trimm One looks very much like a smartphone. Sadly, though, it doesn’t operate like one. For a start, it doesn’t have a touchscreen. Fortunately, these are issues that can likely be fixed with a firmware update, but until then they will almost certainly be dealbreakers for anyone who rides with a power meter .

Note how the chain is as close to the inner plate of the front derailleur as possible without touching. Kaden Gardener / Our Media So often, we see people putting too much power into their pedals as they climb up a steep hill in the big chain ring or legs flailing as they spin out on a gear that is too easy for the descent they are riding. Your goal while riding should be to keep a cadence (the speed at which your pedals make a full rotation) that as consistent as possible! To do that, it requires one of two things: shifting or increased power output. The thing about power output is, unless you are wonder woman, you have a limited supply. We suggest shifting often for increased efficiency while riding. Fortunately, re-uploading these rides more recently (around a month after the rides took place) all of these issues appear to be fixed, except for calories burned, so it looks like Trimm has adjusted things.There are rubber feet but they don’t seem to do much. Also, the highest level of resistance isn’t that challenging. There is more of a gentle gradient between lowest and highest for complete novices or those rehabbing injuries. I’m not a fan of the included out-front mount, though. My first impressions of it were that it looks and feels a little cheap, especially compared to the device itself.

One minor concern is that the length of cord to the solar panel is very short, which limits placement options. You may need to reorganise your other accessories to make room for it.

We’ll now set the high limit screw to prevent the chain from shifting off the cassette into the driveside dropout. One of the most difficult things about learning how to shift is the terminology. Low/High, Big/Small, Easy/Hard, Fast/Slow, Front/Rear, One-by, Two-by, Three-by… if your head is spinning already, you may want to brush up on the following vocab words: A small crosshead screwdriver or hex key. Many Shimano derailleurs use a JIS head. A JIS screwdriver is recommended but not essential. It’s great that Trimm is supporting the One with regular fixes and new features, but it would be preferable if firmware updates were optional rather than automatic. Then you could choose to do it at a convenient time rather than have it forced on you right before a ride. Trimm Cycling app

An argument could be made that the One’s feature-set is streamlined to prioritise what most cyclists actually use on a regular basis, but it’s hard to shake the feeling you might be paying more for less. Firmware updates

There is nothing in the specification that highlights any special features or programming for upgrading your workout. Trimm hasn’t revealed exactly how this works, but we suspect it may switch to a lower sample rate for GPS data on the device and uses your phone’s GPS signal to fill in the gaps. Adjust the cable tension until the chain runs smoothly on the second cog. Kaden Gardener / Our Media Intended primarily to meet the needs of touring cyclists, and looks aside, the Trimm One’s key selling points are smartphone integration and a 15-hour claimed battery life – that can theoretically be made unlimited through the use of ‘smart battery management’ and a couple of optional accessories. With the chain in the smallest cog on the cassette, it should be as close to the outer plate of the front derailleur without touching. Kaden Gardener / Our Media
