Our review

It's early days, but the Trance is a whole lot of fun and it doesn't have any obvious omissions in its spec
Pros: Oodles of power on tap, simple un-distracting head unit, hard to fault spec
Cons: Reach is fairly short for a medium, there’s no ignoring the weight

The Trance E+1 Pro is the second-tier model in Giant’s trail e-MTB range. With 140mm of rear travel, the Trance sits between the shorter-travel Stance and the rowdier Reign, the latter a full-bore e-enduro machine.


Like other Giant e-bikes, the Trance is powered by a Yamaha-sourced SyncDrive motor system, with a hefty 500Wh battery on board.

As a recent convert to e-MTBs, I’m hugely excited to be riding this for the rest of 2020. I’m looking forward to being able to ride straight to the trails from my house, and using the Trance to work on my sub-standard skills.

Giant Trance E+ 1 Pro specification and details

While this isn’t the top spec model, the E+1 Pro gets a fairly generous spec, with decent Fox suspension bits (no gold Kashima-coat bragging rights, but you can’t have everything), Shimano Deore XT drivetrain components and brakes.

The frame itself is aluminium with a forged composite rocker arm, and it employs Giant’s well-established Maestro suspension platform, a four-pivot point design that makes various claims about pedalling efficiency, big- and small-bump versatility, and brake independence.

The Trance is powered by the latest incarnation of Giant’s SyncDrive Pro motor made by Yamaha, which claims to offer up to 80Nm of torque. 

Energy comes courtesy of a large 500Wh battery that’s integrated neatly into the down tube. The level of assist is controlled via a minimalist RideControl ONE head unit mounted on the bar, which imparts information using an assortment of LEDs rather than a screen. 

Unsurprisingly, the Trance E+1 Pro is not a lightweight machine – this medium bike weighs 24.6kg with pedals and a bottle cage, almost half my body weight.

Giant Trance E+ 1 Pro geometry (size M)

Giant’s trail bikes aren’t known for fighting at the front lines of the geometry wars, and the Trance E+ 1 Pro continues in that vein, with a pretty conservative reach figure of 442mm for a size medium and 584mm of stack. 

The 66.5-degree head angle is pretty standard for the category and while the 335mm bottom bracket height isn’t all that remarkable, it’s worth noting that the motor unit is quite bulbous, meaning that the first part of the bike to ground-out on trail obstacles will be the frame, rather than the chainring as you might assume.

  • Head angle: 66.5 degrees
  • Seat angle: 74 degrees
  • Chainstay: 470mm
  • Seat tube: 445mm
  • Top tube: 610mm
  • Head tube: 100mm
  • Bottom bracket drop: 15mm 
  • Bottom bracket height: 335mm
  • Wheelbase: 1,210mm
  • Stack: 584mm
  • Reach: 442mm

Why did I choose this bike?

Last year I went hard on the e-MTB Kool-Aid and I was keen to spend some time with one and find out what it’s like to live with. 

I love that I get myself to the trails fairly quickly without driving or burning excessive amounts of energy dragging knobblies along on tarmac, and I also appreciate how an e-MTB lets me focus on the fun stuff and spend less time grinding slowly up hills.

I’ve ridden a few of Giant’s e-bikes and liked them, and I’ve also spent some time with the standard Trance, so the electrified version seems like a natural choice. 

The longer-travel Reign might be the more exciting looking machine, but even with electric assistance to negate the effort of propelling its extra weight up hills, it just seems like overkill for the rather undramatic riding I tend to do. 

Why the E+ 1 Pro spec for the Trance? It would have felt a little entitled to request the range-topping E+ 0, so I’ve compromised on the second-tier bike, which, fittingly, costs the same amount of money as my ageing estate car did a couple of years ago. 

It remains to be seen which is the more useful machine…

Giant Trance E+ 1 Pro initial setup

I have a well established and deeply flawed setup routine for mountain bikes which involves putting slightly more than the minimum amount of air allowed in the fork (because I weigh 53kg) and pumping up the shock until it sorta-kinda feels about right. 

This is a process born of deep impatience and a lack of moral rectitude and yes, I will do a better job getting things just so in time. I promise.

Otherwise, I threw on a set of older Shimano XTR M985 trail pedals, a bottle cage and a Garmin mount, checked there was sealant in the tyres (there was) and declared the Trance ready for action. 

Bottle barely fitting in front triangle

One little quirk struck me: even with a side-loading cage, there’s somehow still not quite enough space in the front triangle for a bottle.

A 500ml-ish bottle just fits, but it’s pressing against the underside of the top tube and will probably scuff the paint in time. I did try applying a protective sticker to prevent this, but it fell off almost immediately. 

I’m aware that the sultans of shred who buy this bike will mostly use hydration packs, but I prefer my water with a sprinkling of dirt, so I’ll probably just have to live with it. So it goes. 

Giant Trance E+ 1 Pro early ride impressions

The Trance is a pretty complete bike from the box, with no obvious spec deficiencies.
Matthew Loveridge / Immediate Media

It’s early days with the Trance, but it’s already reminded me how much I love e-MTBs, and also how no amount of clever suspension technology can disguise a raw lack of talent. 

This has been a winter of relentless rain and the trails round my way are feeling rather sorry for themselves, with plenty of deep muddy ruts and icy, bottomless puddles. 

I’ve already managed to stack it fairly hard on a particularly slippery section of trail and, while it’s possible a set of more bog-friendly tyres (Schwalbe Dirty Dans or Maxxis Shortys, perhaps) and/or a softer compound (these tyres use the intermediate 3C Maxx Terra option, Maxxis also makes a softer 3C Maxx Grip) might help me stay upright, there’s no cheating physics.

Cranks of e-bike
Giant specs a steel chainring for durability. As you can see, I’ve already started to ruin the finish on the crank arms.
Matthew Loveridge / Immediate Media

With the assist turned up to maximum (or even the second-highest setting), the Trance is almost obscenely rapid up hills, and it powers through sticky mud that I wouldn’t even attempt to ride on a standard bike. 

The motor offers no unpleasant surprises, but I do find it works best to back off the assistance a few notches when descending, to avoid being pinged forwards with every turn of the pedals. 

Also, as with previous Giants, the bike judders when you rest a foot on the pedal at junctions as though it can’t wait to get going. This is mildly irritating, but it’s the flip side to a very responsive system that kicks in almost instantly as you start pedalling.

Cockpit setup
I’m still getting things dialled but early impressions are very favourable.
Matthew Loveridge / Immediate Media

The biggest question mark for me with the Trance is the geometry.

At 174cm (5ft 8.5in) tall I chose a medium by default, but looking at the none-too-long reach figures I was tempted to opt for a large, and I’m still wondering if I made the right choice. 

I don’t feel like I’m riding a bike that’s too small for me, but equally I don’t have that sitting-in-the-bike feeling that’s become a review cliché. 

Given how much seatpost I have protruding from the frame, I might have got away with the large, although Giant fits a longer travel dropper to the bigger bike (150mm rather than 125mm), so it would be a close thing.

In any case, I’m loving the Trance so far, and I’m looking forward to the weather improving.

Giant Trance E+ 1 Pro upgrades

Front tyre
Even more aggressive tyres might help in current riding conditions, but they’re not going to disguise my lack of skill.
Matthew Loveridge / Immediate Media

With no glaring holes in the Trance’s spec, I don’t feel compelled to make big changes at this early stage. 

A change of tyres would likely be the best bang-for-buck upgrade given the state of the trails, but the current rubber combo is a good all-rounder.


Getting the suspension set up properly is my priority and apart from that I just need to conquer my fear of low-friction surfaces and ride this bike as much as possible.
