Most standard e-Bikes weigh between 20 and 25 kilograms, or around 45 to 55 pounds. Performance-oriented e-MTBs are on the lighter side despite the added suspension, ranging from 15 to 28 kilograms. Folding e-Bikes designed for commuters usually weigh around 20 kilograms for portability. On the heavier end, electric cargo bikes tip the scales at up to 40 kilograms.
How Much Do Electric Mountain Bikes Weigh?

E-MTBs are chunkier on the scale than standard bikes, but that extra heft beefs up performance. Here’s everything you need to know about electric mountain bike weight.

Electric mountain bikes put on the pounds to pack a punch. It’s clear that the motor and battery add weight— but just how much do e-MTBs weigh and are those extra kilos really worth it?
Weight comparison: standard vs. electric mountain bike
The average mountain bike weighs around 20 to 35 pounds (9-16 kg), depending on bike type, frame size, and heavy parts like suspension. Electric mountain bikes typically weigh between 40 to 60 pounds (18-28 kg). On average, a high-quality motor and battery will add around 13 to 15 pounds (6-7 kg) to a bike’s overall weight.
Bikes with shorter suspension and parts designed for lighter terrain weigh less, such as cross-country mountain bikes and hardtail e-MTBs. Full suspension models and downhill bikes have longer suspension travel and beefier components— high-torque motors and long-range batteries will also add weight.

How bike weight affects performance
Anyone who tells you that the relationship between bike weight and performance is simple is lying. Lightweight isn’t always better, nor is sacrificing weight for more power or range always worth it— there are additional factors and needs at play.
Most e-MTBs have mid-drive motors that place the added weight low and centrally on the bike. This preserves the handling you’d expect from a standard MTB, but you still may notice the extra heft when riding more technical stuff. Cutting on weight can improve uphill performance and efficiency, but rider weight and motor power can make more of a difference than overall bike weight.
And if you want more speed on the climbs, pace on the descents, and additional range, that means a heavier bike. Added weight will come from high-torque motors, additional suspension, and larger batteries that deliver those performance boosts. The ideal bike weight depends on how you ride and where you’re headed. And remember that bike weight isn’t everything— suspension design and geometry make a huge difference, capable of making heavy bikes feel light and lightweight models ride like lead.

Lightweight e-MTBs: a fad or the future?
There’s been tons of talk about lightweight electric mountain bikes as of late. These are models that weigh less than 40 or 45 pounds (20 kg), providing sufficient oomph on the trails and featherweight agility for technical riding. Things like carbon frames, smaller batteries, and medium-torque motors balance weight savings with off-road performance.
But is opting for a lightweight e-Bike the right choice? Lightweight e-MTBs typically feature shorter range and shorter suspension travel. There are impressively light models around the 18 kg mark from brands like Cube, Mondraker, Specialized (Levo SL), Giant (Trance Advanced), and Trek (Fuel EXe). These light trail rippers are often designed with range extender batteries in mind. But if you need longer range and bigger performance, there are more powerful models that weigh just 23 kg.
Lightweight electric mountain bikes are definitely a marketing jackpot, but aren’t necessarily the ultimate ride. I recommend that you don’t get caught up in the numbers game and obsess about a few grams here or there because, as mentioned, there are other factors that make a difference on the trail. A big technology jump made it possible for e-MTBs to shed serious weight a few years back, but it’s certain that electric bikes are gradually getting lighter across the board as motor and battery tech advance.

Frequently Asked Questions
How much do e-Bikes weigh?
How much should you spend on an electric mountain bike?
Between $2,500 and $3,000 hits the sweet spot for entry- to mid-tier electric mountain bikes. That price range opens up the range of e-MTBs from top brands like Trek, Giant, Specialized, and others with innovative designs and quality parts. Models that fall into that price range are typically hardtail mountain e-bikes or pre-owned full-suspension models.
Spending less than $2,000 means the e-bike will likely come with a rear hub motor, less premium mid-drive unit, or an external battery. Riders can browse the best mountain bikes for under $2,000 designed for recreational riding and lighter mountain biking.
Where can I find trails that allow electric mountain bikes?
Apps such as Trailforks have an e-MTB filter to find routes that allow electric mountain bikes. E-Bike owners can filter the Trailforks map on the website or app to show trails where e-MTBs are permitted.
Key Takeaways
- Electric mountain bikes typically weigh 40–60 lbs, with motors and batteries adding 13–15 lbs over standard MTBs.
- Weight affects performance, but it’s not everything—geometry, suspension, and rider style matter just as much.
- Lightweight e-MTBs are trending, offering agility and range extenders, but often compromise power or suspension travel.
