Building upon a rich history in mountain and road biking, Giant Bicycles hasn’t shied away from delving into the world of e-bikes. Almost as vast as the rest of the brands offerings, the e-bike range covers everything from hard-hitting enduro rigs right up to purpose-built gravel e-bikes. Here’s everything you need to know about Giant Bicycles’ e-bike range.
De un vistazo
Understanding Giant’s naming system
Unlike Giant’s mountain and gravel bikes, the naming system for the range of e-bikes is fairly simple. With exception of the Trance E+ and the Reign E+, each model gets a standard and a Pro model, the latter benefitting from a nicer build kit.
As for the Trance E+, there’s a standard model and then the ‘X’ model which gets a bump in travel, a bit of a geometry tweak, and a flip-chip, just like it’s acoustic counterpart.
It’s worth noting that all Giant e-bikes come with Giant’s own SyncDrive motor that’s been developed in coordination with Yamaha.
Prices for Giant’s e-bikes start at £2,000 and go right up to £7,150. Of course Giant also has a full range of mountain bikes (our guide on those can be found here) and gravel/adventure bikes (click here for that guide).
Kicking things off with the Reign E+. It’s Giant’s enduro bike built for the toughest terrain with 170mm of travel at the front with 160mm at the rear. It hasn’t yet seen an updated for 2020 but it’ll be sacrilege not to include it anyway. It comes in three sizes from S up to L and it gets a 64.5° head angle with a 475mm reach on a large frame. There’s a 76° seat tube angle and a 470mm chainstay. The Reign E+ rolls on 650b hoops.
Reign E+ 0 Pro 625Wh version
The Reign E+ 0 625Wh version is the most expensive in the whole of Giant’s pedal-assisted range. Built around Giant’s ALUXX SL grade aluminium frame, it gets a Giant Syncdrive Pro motor with an EnergyPak Smart 625 battery, also from the same brand. The controller is also Giant’s own. As for the suspension, it’s provided by Fox at both ends on this bike. At the front, there’s an e-bike optimized Fox 36 Float Factory with a GRIP 2 damper and a Fox Float X2 Factory with an EVOL large volume sleeve handling the rear squish. Driving the bike is a SRAM XO1 AXS wireless drivetrain paired with a SRAM Reverb AXS dropper post. There’s also a chain guide from MRP and the V3 but its custom moulded for this bike. SRAM also handles the brakes with the Code Rs with a 220mm rotor at the front and a 200mm disc at the rear. The bike rolls on a pair of Giant e-TRX wheels with a 30mm internal width and they’re wrapped with a Maxxis Minion DHF 2.6″ EXO+, 3c Maxx Terra at the front with a 2.6″ Highroller at the rear with DoubleDown and the 3c Maxx Terra compound. Then the finishing kit comes from Giant.
Reign E+ 0 Pro
Everything on the Reign E+ 0 is exactly the same as the 625Wh version apart from (yep, you guessed it!) the battery. This bike downgrades slightly and gets a 500Wh battery which comes in the form of Giant’s EnergyPak Smart 500, 36V 13.8AH intergrated Lithium-Ion.
Reign E+ 1 Pro
The Reign E+ 1 sees a drastically lower price than the higher-end models. As such it drops the wireless shifting in favour of a Shimano Deore XT 12-speed drivetrain with matching 4-piston brakes. There’s also the same MRP V3 moulded chain guide. This bike gets a Fox 36 Performance fork with a Micro Adjust Grip damper. At the rear, there’s a Fox Float X2 Performance with the large volume EVOL sleeve. The Reign E+ 1 rolls on Giant e-TR1 wheels with a 2.6″ Maxxis Minion DHF with EXO+ and 3c Maxx Terra with a 2.6″ Highroller kitted with a DoubleDown casing a 3c Maxx Terra compound. The finishing kit and dropper post are supplied by Giant.
Reign E+ 2 Pro
Rounding off the Reign E+ line up is the cheapest 2 model. It gets a Fox 36 Float Rhythm with a GRIP damper and a Fox Float DPX2 with an EVOL large volume sleeve. This bike gets a SRAM GX Eagle 12-speed drivetrain with the same brand’s Guide RE four-pot brakes. It rolls on Giant AM7 27.5+ rims with a 35mm internal width and comes kitted with the same tyres as the rest of the range. The rest of the bike is finished off with Giant’s own kit.
The Giant Trance E+ comes in two models only one of which seeing an update for 2021. There’s no difference between the Trance E+ and Trance X E+ in terms of travel, like the unassisted models but the Trance X E+ gets a geometry adjusting flip-chip, 29″ wheels and a 625Wh battery as standard. The standard Trance E+ hasn’t seen an update for 2021 but it rolls on 650b+ wheels and gets a 66.5° head tube angle with a 460mm reach on a large. Then there’s a 74° seat tube and a 470mm chainstay. The Trance X E+ in its low setting gets a 65.8° heat tube angle, a 480mm reach (on a large), a 76° seat tube angle and a 472mm chainstay. Both bikes come with 150mm of travel at the front and 140mm at the rear.

Trance E+ 0 Pro 625Wh version
The Trance E+ 0 Pro 625Wh version tops the whole of the Trance range. It gets a beefier 625Wh batter with a Fox 36 Float Factory with a FIT 4 damper. Handling the rear suspension is a Fox Float DPX2 Factory with the large volume EVOL sleeve. It’s built around an aluminium frame and is drive by a SRAM XO1 Eagle drivetrain with SRAM Code R brakes. This bike also gets the MRP V3 custom moulded chain guide and it rolls on Giant e-TRX wheels with a 35mm internal width. As for the tyres, they’re the same as what you would find on the Reign E+, a Maxxis Minion DHF 2.6″ at the front and a 2.6″ Highroller at the rear. The rest of the bike, including the dropper post, comes from Giant.
Trance E+ 0 Pro
Very much like the top end Reign E+ models, this is the exact same bike as the range-topper but with a 500Wh battery which will save you around £150.
Trance E+ 1 Pro 625Wh version
The Trance E+ 1 Pro 625Wh version offers a pretty significant saving versus the 0 model. It gets that same 625Wh battery but it sees a slight downgrade in spec. The fork on this bike is a Fox 36 Float Performance EVOL with a GRIP damper and the shock is a Fox Float DPX2 Performance with the large volume EVOL sleeve. This bike gets a full Shimano Deore XT Drivetrain with matching four-piston brakes, there’s also that MRP V3 moulded chain guide. This bike gets a Praxis Wavetm crank with a 36t chainring. It rolls on Giant’s own e-TR1 wheels with a 30mm internal width and the same tyres as the rest of the range. Giant also finishes off the bike with the brands own kit.
Trance E+ 1 Pro
The Trance E+ 1 Pro benefits from all of the same kit as the 625Wh version but it doesn’t get that bigger battery but instead Giant has opted to fit the slightly smaller EnergyPak Smart 500 unit.
Trance E+ 2 Pro
The Trance E+ 2 uses the exact same motor and battery as the non-625Wh bikes and uses a Fox 36 Float Rhythm with a 44mm offset, EVOL and GRIP damper. Providing the rear squish is a Fox Float DPS with an EVOL large volume sleeve. The bike is then driven by a mix of Shimano SLX and XT with an XT mech and SLX shifter. There’s also an MRP 1x CS Custom chain guide to keep it in check. There’s a Praxis Wavetm crankset with a 36t chainring too. As for brakes, they’re Shimano BR-MT520 four-piston callipers hooked up to BL-MT501 levers. Wheels come from Giant and the AM 27.5+ rims on Shimano centre lock hubs. Then they’re wrapped with a Maxxis Minion DHF 2.6″ EXO, dual compound at the front and a Maxxis HighRoller II with the same specs. The rest of the bike is provided by Giant.
Trance E+ 3 Pro
Rounding up the Trance range and costing the least is the Trance E+ 3 Pro. This one gets a RockShox 35 Gold RL DebonAir fork with a Fox Float DPS Performance with an EVOL large volume sleeve at the rear. There’s a full SRAM Eagle SX drivetrain and four-piston Tektro HD-M745 Orion brakes. The crank here is a SRAM X-Sync Eagle with a 38t chainring. This bike gets the same wheelset and tyres as its slightly pricier superior and the finishing kit comes from Giant.
Trance X E+ Pro 29 1
The range-topping Trance X E+ Pro 29 1 runs on the 625Wh battery and gets a Fox 36 Float Performance Elite with a FIT4 damper. At the back there’s a Fox Float DPX2 with an EVOL large volume sleeve. This bike benefits from a Shimano drivetrain with a mix of XT and XTR parts the former sorting the shifter and latter, the derailleur. There’s also an MRP 1X Custom V3 chain guide. As for the crankset, it’s a Praxis Wavetm with a 36t chainring. Giant supplies the wheels with the e-TR1 wheelset and there’s a Maxxis Assegai 2.6″ EXO 3C Maxx Terra on the front, paired with a Maxxis Dissector 2.6″ with EXO+ and a 3C compound. As with the rest of the bikes, the handlebar, stem and dropper come from Giant.
Trance X E+ Pro 29 2
While the Trance X E+ Pro 29 sees quite a significant drop in price, it’s still got a pretty sorted spec. The fork on it is a Fox 36 Float Rhythm and there’s a DPS performance shock with an EVOL large volume sleeve at the rear. There’s a Shimano SLX shifter paired with an XT mech and there’s an MRP 1X custom V3 chain guide. It gets the same crank as the spendier bike but it gets slightly cheaper Giant AM 29″ rims on Shimano hubs, wrapped in the very same tyres as the range-topper. The finishing kit comes from Giant.
Trance X E+ Pro 29 3
The Trance X E+ Pro 29 3 sits cheapest of the Trance X range and as such it gets a RockShox 35 Gold RL DebonAir fork with a Fox Float DPS Performance EVOL shock. In line with its price, this one sees a Shimano Deore drivetrain with the same MRP chain guide as the other bikes. As with the rest of the bikes, it gets a Praxis Wavetm crankset with a 36t chainring. This one rolls on a set of Giant AM 29″ wheels on Shimano MT410 hubs and it gets the same tyres as the others in the range. The finishing kit is done by Giant.
Just like its acoustic counterpart, the Giant Stance E+ is the brand’s trail bike with 120mm travel that comes from a FlexPoint suspension platform. It comes kitted with a 130mm travel fork and the bike comes in a standard and a Pro model. The pro model gets a slightly higher spec and as such is a little pricier. Both models of the Stance E+ receive a 67° head angle, a 73.5° seat tube angle and a large frame has a reach of 444mm. As a slight deviation in Giant’s naming conventions, wheel size isn’t mentioned in the title but the Stance E+ run on 29er wheels.
Stance E+ 1 Pro
The Stance E+ 1 Pro gets Giants bigger 625Wh battery with a RockShox Recon Silver RL fork and a RockShox Monarch RT high volume shock. It comes with a Shimano Deore drivetrain with matching brakes. This bike gets the exact same crankset as the Trance E+ range but comes with Giant’s own XCT 29 rims laced to Shimano MT410 boost hubs. The tyres on this one come from Maxxis with a Minion DHF 2.5″ EXO at the front and a DHR II EXO at the rear. The finishing kit is provided by Giant.
Stance E+ 2
As the cheapest full suss e-mountain bike the Stance E+ 2 comes with a bare-bones, no-frills build kit. There’s no dropper on this one and the fork gets downgraded to an SR Suntour XCR 34 air fork. The shock here is a RockShox Monarch R and there’s a Shimano Deore 10-speed drivetrain with an MRP 1X CS Custom chain guide. Brakes are provided by Tektro and the HD-M745’s. The crankset is unbranded and this bike rolls on the same wheels as it’s more expensive sibling but they’re laced to Giant’s own hubs. Tyres on the Stance E+ 2 are Maxxis Recons in their 2.4″, EXO guise. Everything else comes from Giant.
The Fathom E+ 29 is Giant’s hardtail e-mountain bike. In this range, there are two bikes, the standard and the Pro, the latter benefitting from a larger capacity battery with some spec and geometry tweaks. The former comes with a 68° head tube angle, a 475mm chainstay, a 73° seat tube angle and a large comes with a 428mm reach. The Pro model gets a slacker 66° head tube angle a 467mm reach and it drops the XXL frame size. The fork allows for 120mm of travel on the standard model and the Pro gets an extra 10mm.

Fathom E+ Pro 29 2
The Fathom E+ Pro 29 2 gets Giant’s sizey 625Wh battery with an SR Suntour Raidon 34 Boost Air LOR fork. The drivetrain on it is a Shimano Deore 11-speed set up with BR–MT200 brakes from the same brand. As with many of Giant’s other e-bikes, this one benefits from a Praxis Wavetm crankset with a 36t chainring. The wheels are Giant XCT 29’s and they’re laced to Giant eTracker Boost hubs. As for the rubber, there’s a Maxxis Minion DHF 2.5″ EXO on the front and a Maxxis Aggressor 2.5″ WT EXO at the back. The finishing kit is done by Giant.
Fathom E+ 29 2
The Fathom E+ 2 29 rounds off Giant’s e-mountain bike range. It’s the cheapest the brand offers and it comes with a 500Wh battery with an SR Suntour XCR 32 Boost Coil with a Shimano Deore 10-speed drivetrain. The brakes also come from Shimano and the BT-MT200’s. The crankset is unbranded and this bike uses the same wheels as the Pro model. Both tyres on this bike are Maxxis Recon 2.4″ EXO’s and the finishing kit comes from Giant.
The Giant Revolt E+ Pro is the only purpose-built gravel bike in Giant’s line-up and it hasn’t had an update for 2021 yet. It runs on a smaller 375Wh battery and comes in three sizes from S up to ML. Geometry-wise, there’s a 71° head tube angle, a 73° seat tube angle, 455mm chainstays and an ML frame gets a 386mm reach.
Revolt E+ Pro
There’s only one Revolt in the range, making choosing your bike a little easier. This one gets a Shimano GRX 1×11 drivetrain with matching brakes. There’s Giant’s own crankset with a 42t chainring and it rolls on Giant eX 2 rims laced to Giant hubs. Tyres come from Giant in the form of the CrossCut Gravel 2, 700x45c’s and the finishing kit also comes from Giant.
Giant Explore E+
The Giant Explore E+ comes in two main models, the standard E+ and then the E+ Pro. Both models come with two build kits with unisex and women’s specific options available. The difference between the standard and Pro models are primarily in the battery with the Pro coming with a 625Wh unit and the standard a 500Wh. It’s built to be as capable on the road as it is on fire roads and light trails, being kitted with a fork with 60mm of travel. The geometry changes from both models too. Women’s models are defined by the word ‘Stagger’ in the title, presumably referring to the dropped downtube.
Giant Explore E+ Stagger geometry sheet
Explore E+ 0 Pro
This Explore E+ Pro 0 gets an RST Pulse 29-15 AIR fork and a Shimano XT 12-speed drivetrain with matching brakes. The rims are Giant eX 2’s laced to Giant eTracker hubs and wrapped in Giant CrossCut 700x45c tyres. The rest of the bike is finished off with Giant’s own kit. Pictured is the Stagger model, but the standard model comes with all of the same kit. The lights fitted are Supernova E3 Axa at the front with a BlueLine Steady E6 rear and there are MIK racks.
Explore E+ 1 Pro
The Explore E+ 1 Pro has an SR Suntour NCX D AIR LO with 63mm of travel. Driving the bike is a Shimano Deore drivetrain with BR-MT410 callipers paired with BL-MT1400 levers from the same brand. Wheels and tyres come from Giant and they’re exactly the same as what you’ll find on the Explore E+ 0 Pro, as is the finishing kit. Lights on this one are Axa BlueLine 50Lux Steady E6 front Axa BlueLine Steady E6 rear. Again, there are MIK racks. The Stagger model gets the same specification
Explore E+ 1
The Explore E+ 1 gets a slightly smaller 500Wh battery with a Shimano Deore 10-speed drivetrain. The brakes are also supplied by Shimano and the BR-MT200 callipers mated to BL-MT200 levers. The wheels and tyres are the same as the rest of the range and the finishing kit comes from Giant. The lights fitted are Axa BlueLine 50Lux Steady E6 front Axa BlueLine Steady E6 rear and it comes with MIK racks. Stagger models come with the same kit.
Explore E+ 2
Finishing off the Explore E+ range is the Explore E+ 2. It gets an SR Suntour NEX E25 DS fork, Shimano Alivio mech with an SL-M2000 shifter and MT-200 brakes. Wheels, tyres and lighting is the same as the other models in the range and the finishing kit comes from Giant.
Rounding off the whole of Giant’s e-bike range is the Roam E+. It’s built to get you going along roads, bike paths and light trails. Just like the Explore E+, the Roam comes with a unisex and a women’s specific Stagger model. Not a lot sets either bike apart from each other apart from the Staggers low standover and the fact that the unisex model comes in four sizes, rather than the Staggers three, it misses out on an XL.
The Roam E+ gets an SR Suntour NEX E25 fork with 63mm of travel with a Shimano drivetrain, consisting of an Alivio derailleur and an SL-M2000 shifter. This bike rolls on Giant GX03V 700c rims with Giant CrossCut tubeless ready tyres. Then the finishing kit is supplied by Giant too. The Stagger model gets the exact same spec but with that lower standover.
