Momentum Vida E+ EX review: comfort, class and a clever dropper post

So many electric bikes never let you forget the electric bit. The Momentum Vida E+ EX is the opposite. Momentum has poured decades of cycling know-how inherited from parent company Giant into a machine that, first and foremost, rides like a really good bicycle, and that makes it a commuter almost anyone can get along with.

At $1,985, which converts to roughly £1,500 before local taxes and homologation, the EX takes the standard Vida E+ and adds three upgrades: a dropper seatpost, a 0-start throttle and built-in cruise control. It went on sale through the Giant Group dealer network on 14 July 2026 as a 2026 model. Its natural rivals are upright, step-through town bikes such as the Volt Burlington, the Electra Townie Go! S and, at the budget end, the Puckipuppy Poodle.

One important note for British readers before we go any further. The Vida E+ EX is a US-market machine, configurable between American Class 2 and Class 3 settings via the RideControl app, which means assistance up to 28mph and an optional $65 throttle. That puts it well outside the UK’s EAPC rules, which cap motors at 250W continuous and assistance at 15.5mph, as the government sets out in its electric bike guidance. No UK price or on-sale date has been confirmed, so read this as an international review of where Giant’s thinking is heading rather than a buying guide for British cycle paths.

Comfort first, and it shows

The first thing that struck me was how comfortable this bike is. Momentum has gone after a low, approachable step-through with Dutch bars and a deliberately short reach, and the payoff is a riding position that keeps your head up and your back happy without ever feeling like a stretch. Plenty of bikes attempt this and still leave you leaning forward and off balance. This one does not.

At 5ft 11in with a 3oin inseam, the large fitted me perfectly, and the two sizes genuinely cover riders from 5ft 1in to 6ft 3in, which is rare. Riders around 5ft 8in or 5ft 9in get a choice: the small for a nimbler feel, or the large for a stable, Cadillac-style glide. The 720mm handlebar with its 20-degree back sweep sits in the sweet spot, neither cranking your wrists nor loading your palms, and the ergonomic grips make it a pleasant place to spend an hour.

Despite the relaxed posture, the ALUXX aluminium frame is stiff enough to feel sporty when you push on, helped by an SR Suntour XCM34 coil fork whose 34mm stanchions are chunkier than the 30mm or 32mm units common at this price. Combined with a 15×110 thru-axle, the front end feels planted and secure.

My favourite feature, though, is one you almost never see on a Dutch-style commuter: a Giant Contact Switch AT dropper post with 110 to 140mm of travel. Roll up to a red light, drop the saddle with a crisp flick of the lever, and you can stand flat-footed without climbing off, then pop it back up as the lights change. It is borrowed from mountain biking and it transforms stop-start town riding. Droppers can be finicky, but this one has been faultless, and it is two or three steps better than anything I would expect at this money.

Two fit niggles. The stem is not adjustable, although the handlebar angle is, and the left side of the cockpit gets busy with the display, brake lever and dropper lever sharing space. Have your dealer set it up at purchase and it becomes a set-and-forget arrangement.

Power that feels bigger than the spec sheet

The EX runs a 500W nominal, 750W peak SyncDrive Move S rear hub motor with 60Nm of torque, a healthy step up from the 350W unit fitted two Vida generations ago. On paper that is mid-pack. On the road it feels like considerably more, because Momentum blends a torque sensor with speed and cadence sensors and an algorithm tuned to make pedalling feel utterly natural. Power arrives within a sixteenth to an eighth of a pedal turn and cuts the instant you stop, with no surge and no overrun. It is one of the most precise rear hub systems I have tested recently, which is saying something given how good hub motors have become over the past two years.

On the flat it simply does not feel like a 500W bike. It tapers power smoothly off the line rather than launching you, yet has no trouble holding Class 3 speeds, and I genuinely forgot it was not a 750W motor until our hill test. Even our videographer, who tips the scales at over 275lb with his camera kit aboard, remarked on how quick and fun it felt. The Eco, Active and Power modes are clearly separated and predictable, and Eco is a properly usable setting rather than one gamed for range figures.

Hills expose the limits. Our test climb is 0.35 miles of long, steep gradient with a brutal final pitch. On throttle alone the bike covered 0.3 miles at an average of 8.6mph before giving up after 129 seconds, just yards short of the top. Under pedal assist it completed the full climb in 135 seconds at 9.6mph average, though I had to work on that last section. That is exactly what 500W and 60Nm should deliver. If you want to torch climbs like that, you need 750W and 85 to 90Nm.

The Energy 700 battery is a 48V, 14.7Ah, 700Wh pack that is UL 2271 certified, with the complete system carrying UL 2849 approval, the standard covering the entire electrical drive system. Momentum claims 40 to 55 miles on pedal assist and 31 to 43 on throttle, and our testing backs that up: just over 34 miles on maximum assist and 58.5 miles on minimum. For a daily commuter, that means most riders will charge once a week.

Components that punch above the price

Momentum has specified a Shimano Acera 8-speed drivetrain with a 52T chainring and an 11-40T cassette, a step above the Tourney and Altus kit usual at this price. That big chainring means no ghost pedalling either; spinning at 27 to 28mph in top gear had me at a comfortable upper-60s to low-70s cadence. Braking comes from Tektro hydraulics, cleverly staggered with a 4-piston caliper on a thicker 2.25mm rotor up front and a 2-piston caliper on a 1.85mm rotor behind, both 180mm. Hammering them six or seven times down a two-minute descent produced no fade and no sponginess whatsoever.

The Luxe saddle is comfortable and has a built-in carry handle, welcome on a bike that weighs an advertised 66lb (67.6lb measured with tyre slime in our test unit’s 26in x 2.4in tyres). A MIK HD rear rack rated to 55lb and integrated lights with a brake signal come as standard, and the brake light stays visible with panniers fitted, which plenty of bikes get wrong. Total payload is a generous 300lb. My one build gripe is the internally routed headset wiring, which looks clean but adds workshop time whenever the stem, fork or headset is touched.

The minimalist RideControl Dash Core display gives you an accurate battery percentage, speed and the usual trip data, while the RideControl app handles the bigger settings, including dropping the top speed to 20mph and disabling the throttle. There are over-the-air updates and a digital E-Lock that disables motor assistance, though I would like to see per-level motor tuning and theft tracking next.

Verdict

Momentum set out to build a bike for everyone and has largely succeeded. The natural motor feel, dialled-in geometry and that brilliant dropper post add up to a commuter that makes you want to keep riding, and the component package would not look out of place at $2,500. Steep-hill dwellers should look at something with more torque, and UK buyers must wait for a road-legal EAPC version. Everyone else should pay close attention, because this is the direction sensible, well-sorted commuter e-bikes are heading.
