Pedal Power Unleashed: A Deep Dive into Vtuvia’s Gemini Fat Tire E-Bike [A Review]

With a powerful motor, dual-batteries, and a generous collection of included accessories, Vtuvia’s Gemini is a great deal for riders looking for an affordable all-terrain e-bike.

Specifically, this ride comes loaded with a 1000W rear-hub motor that can reach astonishing top speeds and dual-52V batteries for a combined capacity of 1092Wh.

Oh, and the motor has a max torque output of 100Nm, so it’s unlikely you’ll ever come across a hill it can’t handle.

Other notable features include 26″ fat tires, a 7-speed shifter, dual front headlights, hydraulic disc brakes, a rear rack, and an impressive 400 lb payload capacity.

There’s really not much to complain about here, but personally, I don’t love either of the colors the Gemini comes in.

Otherwise, I think the Gemini has a lot to offer for such an affordable e-bike.

Before you decide though, make sure you keep reading – in this review, I’ll go over everything this sporty e-bike has to offer, including a comparison to a few top comps.

After reading, you’ll know whether or not the Gemini is really worth investing in.

With impressive performance specs and plenty of great features/accessories, Vtuvia’s Gemini would make a great option for riders looking for a powerful all-terrain e-bike in the $2k price range.

Vtuvia’s Gemini Fat Tire Electric Bike

Vtuvia’s a California based brand on a mission to provide riders with affordable, versatile e-bikes.

As I’m writing this, they offer 8 or so e-bikes to choose from, ranging from larger all-terrain models (like the Gemini we’re here to talk about now) to smaller, folding models that are easy to travel with.

Several of their bikes have fun names too, like “Reindeer”, “Giraffe”, and “Antelope”, which I appreciate.

I know it doesn’t effect the quality of the bike, but it’s always fun to see interesting names…

Anyway, the Gemini we’re here to go over now is their highest-end e-bike to date. Prices will vary a little depending on promotions and whatnot, but expect to see it going for around $2k, give or take.

Motor

The Gemini comes with a 1000W, rear hub motor that should be able to reach a top speed of well over 30 mph.

This is one of the strongest e-bike motors I’ve come across, but it’s especially strong for a model in this price range.

FYI, “rear hub” refers to the fact that the motor is located in the rear tire – this is as opposed to a “mid-drive” motor which is located in the middle of the frame with the crankset.

Considering most rear hub motors max out around 750W, the Gemini is immediately packing more brute force than most comparable electric bikes.

This wattage is impressive, but the 100Nm (Newton-meters) of torque this motor can create is maybe even more impressive.

Torque refers to the rotational power of the motor and seeing higher torque ratings means the motor will be able to provide faster accelerations and perform better when climbing hills.

Well, a lot of similarly-priced all-terrain e-bikes come with torque ratings in the 65 – 85Nm range.

At 100Nm of torque, you can expect the Gemini to perform highly on any grade of incline you come across, but it’ll also come in really handy when riding on dirt, rock, or any other off-road terrain.

And again, that top speed is realllly fast.

Being able to reach upwards of 35 mph easily makes the Gemini a Class III e-bike, so before you purchase, it’s a good idea to check with your local regs to make sure Class III bikes are street legal.

If you’ll be simply riding on your own property though, you won’t have to worry about it.

Overall, there’s nothing to complain about when it comes to the motor on this electric bike – the Gemini is packing a really strong motor and more than enough torque to handle steep inclines and rough terrain.

Battery

Having a strong motor can be fun, but strong motors pull a lot of power from batteries, which usually cuts your range short.

But it looks like the folks at Vtuvia planned for that.

The Gemini comes with two batteries, giving it a surprisingly impressive range for such a powerful e-bike.

More specifically, this bike comes with 2x 52V, 10.5Ah batteries that integrate nicely into the frame of the bike.

If we do the math, that means each battery provides 546Wh (watt-hours) of energy for a combined capacity of 1092Wh.

This is a huge amount of battery capacity, considering most all-terrain e-bikes in this price range come with battery capacities in the 600 – 1000Wh range.

The fact that Vtuvia uses 52V batteries for the Gemini is worth considering as well.

When compared to the 48V batteries found on many e-bikes in this price range, opting for a bike with 52V batteries offers more power, improved battery life, and better overall performance.

The fact that the Gemini uses 52V batteries is key to the amount of power that rear hub motor can provide.

With 1092Wh of battery capacity, the Gemini could theoretically reach a max range of 80 miles or so between charges, but that would be with a small rider riding on flat pavement while using PAS level 1 the whole time.

Which is unrealistic and kinda defeats the purpose of having a bike like this in the first place.

More realistically, I’d expect most riders to get real-world ranges more in the 30-50 mile range, but that’s still really impressive for an all-terrain bike like this.

Speaking of charging, Vtuvia includes 2x chargers (each standard 2A) so you can charge both batteries at the same time -which is great, because you need to have both batteries charged to get optimal performance and range.

Overall, I’m impressed by the battery capacity of the Gemini. With dual batteries, it offers a generous range for such a powerful e-bike.


Frame

The Gemini only comes in one size and one style (step-over) and with a standover height of 20″, it’s not well suited for shorter riders.

Actually, according to Vtuvia, this e-bike is designed to fit riders who are between 5’8″ – 6’5″, so it really is an electric bike best suited for the taller crowd.

Otherwise, with a weight of 72 lb (and that’s including both batteries), the Gemini is pretty average in terms of weight for this class of e-bike.

It isn’t lightweight, but it isn’t the heaviest e-bike either.

It’s worth noting though, that this bike can handle a payload capacity of 400 lb, which is quite a bit higher than the 275 lb – 350 lb limits seen on many comparable bikes.

FYI, the “payload” capacity refers to the total amount of weight the bike can handle – this includes rider weight and any cargo being hauled.

Otherwise, the Gemini is pretty average in terms of size, coming with a total length of around 73″.

Warranty

Vtuvia covers the Gemini with the following home warranty:

  • 2 year frame
  • 1 year battery/parts

Ok, so this guarantee is pretty short, but to be fair, a lot of the most popular e-bike brands offer similar coverage (Juiced Bikes, Rad Power Bikes, Ride1Up, etc).

Two years on the frame actually isn’t bad, considering a lot of brands offer a blanket 1 year warranty for everything.

But if you look at the fine print regarding Vtuvia’s parts guarantee, you’ll notice that a lot of stuff isn’t covered under that 1 year warranty.

Their parts warranty actually only covers 5 things: the rotors, handle bar tube, throttle, caliper, and brake pads.

And the brake pads are only covered for 3 months.

This means that every other component, including the motor, isn’t covered by any warranty.

So, not a great warranty here, but Vtuvia does also offer a 30 day money back guarantee.

Features

Vtuvia’s Gemini comes with the following included features:

LCD console- this bike comes with a brightly-lit, color console that makes it easy to see your speed, distance, battery level, and other metrics while cruising.

5 levels of PAS- and with 5 levels of pedal assist to work with, you can have as much or as little motor assist as you prefer.

Thumb throttle- the throttle also lets you take full advantage of the motor anytime you want, regardless of PAS level.

7-speed shifter- the Gemini also comes with 7 gears, giving you a lot of control over your pedaling performance.

Hydraulic disc brakes- these brakes offer top stopping power and control and even though they’re becoming commonplace on e-bikes in this class, it’s still a good idea to check.

Fat tires- this bike comes with 26″ x 4″, puncture-resistant tires. With tires this large, the Gemini is well-equipped to handle smoothly while riding over grass, gravel, mud, snow, or any other sloppy terrain you find.

Front suspension fork- you can unlock the front suspension to provide more cushion when riding over bumpy ground or lock it out for a firmer feel as you see fit.

Dual headlights- this bike comes with dual LED lights in the front, making for an exceptionally bright headlight that’ll let you ride safely anytime of day or night.

Rear rack- Vtuvia includes a rear rack with purchase ($79 value), giving you a convenient place to store groceries or any other cargo you might have to haul around. It comes with a 55 lb weight capacity.

Fenders- the included front/rear fenders will help keep you clean when riding over messy pavement or ground.

Phone mount- I think it’s awesome that Vtuvia includes a free phone mount because this is one of the most handy e-bike accessories out there. With a phone mount, you can conveniently use GPS or listen to tunes while you ride.

Comps

Ok, that about does it for everything the Gemini has to offer, but before we wrap things up, I wanna take a look at some of the other top all-terrain e-bikes available in this price range.

Speaking of price, the Gemini comes with a full retail price of around $2399, but it’s on sale for $2099 at the time of writing this.

That may change by the time you read this, but I’ll still be using the ~$2k price point for our comps here.

The first one that comes to mind is Juiced Bikes’ RipCurrent S, which comes with an identical full retail price (but is on sale for $1700 as I’m writing this).

The RipCurrent S is a beast of a bike, coming with a 1000W rear hub motor, a 995Wh battery, and a top speed of 28 mph.

It also comes with a 9-speed shifter, hydraulic brakes, a rear rack, and 26″ x 4″ fat tires.

This e-bike is very similar in specs and features, although the RipCurrent S does come with both a cadence and torque sensor, which some riders might prefer.

It also comes in 3 frame sizes, making it more user friendly for shorter riders.

Another top contender is Ride1Up’s Rift, which is selling for $1695 at the time of writing this.

The Rift is a great looking bike that comes with a 750W rear hub motor with 95Nm of torque, a 960Wh battery, fat tires, an 8-speed shifter, and a max range of somewhere around 45 – 60 miles.

This e-bike comes in both a step-over and step-thru frame, comes with front and rear lighting, as well as a heavy-duty, integrated rack that can hold up to 150 lb of cargo.

It’s a little heavier, weighing in at roughly 85 lb, but it can accommodate riders between 5’1″ – 6’4″.

Finally, I want to mention the RadRover 6 Plus, which is selling for around $2099.

This all-terrain e-bike comes with a 750W rear hub motor, a 672Wh battery, and a top range of somewhere between 25 – 45 miles per charge.

It also comes with 26″ x 4″ tires, a 7-speed shifter, hydraulic disc brakes, and front/rear lighting.

But it doesn’t come with a rear rack and it can only handle riders weighing up to 275 lb.

Final Thoughts

Alright, that’ll about do it.

I really like Vtuvia’s Gemini and I think it’s got a lot going for it.

And as I think the above comps demonstrate, there are a lot of great all-terrain e-bikes in the $2k price range, but the Gemini holds it own with the best of ’em.

This e-bike comes with some great features, but what really stands out to me is the amount of power and battery capacity it’s packing.

It’s unlikely you’re going to find more horsepower in this price range and the fact that the Gemini comes with dual 52V batteries is kinda amazing.

The biggest downside I see is that this is a large e-bike designed for taller riders, so smaller folks may want to consider one of the bikes mentioned above.

It would be nice if Vtuvia offered the Gemini in different frame sizes because that way they’d be able to accommodate a larger population of riders.

It would also be nice if the Gemini came with rear lighting – not a dealbreaker by any means, but it would certainly add to the total package.

All things considered though, I could see the Gemini being a great choice for taller riders looking for a powerful e-bike that can go anywhere.
