Including the key features, pros and cons of this 7-speed 500w electric bike.

California-based Sixthreezero bikes offers a range of men’s and women’s bikes, from stylish beach cruisers to hybrids and women’s-specific electric bicycles. This includes their popular ‘EVRYjourney‘, ‘Around The Block‘, and ‘Ride In The Park‘ models.

Their bikes are known for their classic style: they’re designed in Southern California and many of the frames are vintage-inspired, but built with modern components.

In addition to a selection of beach-inspired color options for the frames (including yellow, aqua, and dark blue), you can also customize your bicycle with their range of matching bags, panniers, and other accessories.

In this Sixthreezero bike review, I provide an overview of the Sixthreezero brand, as well as a more detailed look at my specific bike model, their Ride In The Park 500w 7-speed women’s electric bicycle.

Keep on reading below my review for a close-up image gallery showing all the key features as well as my video review of this e-bike, which provides a real-world look at some of those features and the overall style and build-quality of this cruiser.

Key features

Design and style

With an elegant, step-through frame, the bike is designed to look like a classic. I also like how the battery is hidden away when you have the ‘rear rack bag’ installed.

This makes the ‘Ride in the Park’ electric bike a good choice for a commuter bike too. The Ride1UP Roadster V2 single-speed ebike is also a great option for commuting. Read Alastair’s Ride1UP review to learn more about that stealthy electric bike.

Women’s Sixthreezero electric bike – Ride In The Park model

Like many of the brand’s most popular men’s and women’s bike models, the Ride In The Park model is available in both electric and non-electric versions.

Both look similar, with the most obvious difference being the electric bike’s battery, but even that is not particularly obvious, as it’s hidden on the rear of the bike, over the back wheel.

If you ride your bike with panniers or other accessories on the rear, as shown in some of the photos in this review, then you don’t even notice the battery!

As mentioned above, Sixthreezero bikes come in a range of beachy, vintage-style colors. My bike is Navy, and the other two options for this particular model are Teal and Cream.

The Navy bike has the Teal blue color on the rims, which is a nice touch, and the tires are similar to the Cream color option.

The saddle is well padded and supported with springs, and is very comfortable to sit on. It’s a good size, unlike the very firm, minimal saddles you find on other styles of bike.

You don’t need a tool to adjust it, just unlock the clip below the saddle and move it up or down to your preferred height.

The saddle and handlebars are covered in an attractive tan synthetic leather, with contrasting stitching.

Battery power and life

This e-bike has a 500w motor and 48v battery. This is similar to other electric bikes we’ve reviewed and is powerful enough to provide a good amount of power for riding uphill as well as on flatter roads.

The motor and rear disc brake

As you can see in the demonstration in my video review, it’s a quiet motor – unlike some e-bikes.

The Ride In The Park e-bike doesn’t require you to be pedaling to take advantage of the motor. It has a throttle function that you push with your left thumb to propel you, without pedaling at all.

That said, you will get more mileage per charge out of your bike if you don’t let it do all the work, and do some pedaling as well!

According to Sixthreezero, you should get up to 20 miles per charge when just using the throttle, compared to up to 40 miles with some pedaling. Of course, these stats vary depending on factors such as how much pedaling you do, how hilly the roads are and your weight on the bike.

To charge the battery, you can remove it from the frame. This is great if you don’t have an outlet near where you store your bike. You don’t have to remove it, though – it’s designed so you can plug it in while it’s on the bike, too.

The pedal assist function has five levels. This influences the amount of ‘assist’ you can get from the motor when you pedal, with level five being the fastest.

In addition to the electric motor, this bike has 7 manual gears for regular pedaling.

The top speed I achieved from this bike using just the throttle (full electric, no pedaling), was 17 miles per hour. I believe it could get closer to 20 mph, however the acceleration would take a while to get up to that fast, so 17 is a more realistic expectation.

Braking is smooth and efficient, by virtue of the bike’s disc brakes.

It also has hybrid tires, so while it is designed for use on roads, not off-road, it can handle some rougher (eg gravel) surfaces for short periods, if needed. That said, this particular SixThreeZero bike is not designed for off-road use, and doesn’t have suspension forks.

LCD display panel

The LCD display panel is where you see all the bike’s electric settings, including how much battery charge you have, what pedal assist level you’re on (from level 1 to level 5 – it’s level 2 in the picture below) and your mileage (on the bike in total, as well as since turning it on).

The large, clear LCD display

It’s a nice, large screen that’s easy to read even at a glance.

This was one of the parts that I had to attach when the bike arrived. This is easy – it’s just plug-and-play.

The screen came in a box with what looked like factory specs and instructions from an overseas factory, which was a little confusing and unnecessary.

Size and weight

On Sixthreezero’s website, they have a five-minute fitting quiz you can complete to check what size bike would work best for you and your riding style.

The Ride In The Park e-bike was a fit for me, based on my weight and height. This particular model bike has a weight limit of 300lb and is designed for riders between 5ft 3 and 6ft 2 tall.

While some of their bikes are intended to be more leisurely beach cruisers, the Ride In The Park can be used for longer, more frequent journeys – especially with the electric assist function.

It’s an all-around, versatile option if you’re looking for an electric bike for getting around on… that doesn’t look like your typical electric bike.

Unlike the push-bike version, this electric bike is, however, pretty heavy. This is true of all electric bikes we’ve tested, as the lithium battery adds a lot of weight.

While other bike brands opt to have the battery in the center, on / or in the middle of the frame (in front of the pedals), this bike’s battery is right at the back, over the back wheel.

This means you have to be careful when wheeling it around and parking it – it’s easy to hold the handlebars and have the back of the bike fall over if you’re not careful.

On the flip-side, having more weight at the back means it’s easy to lift the front up, and onto a curb, for example.


If you’ve never bought a bike online, or not purchased an e-bike for home delivery before, you may be curious about what it’s like when it arrives.

The bike arrives in a large box, that requires two people to lift – similar to the box a large TV would come in.

It comes around 80% assembled, with the cranks, motor and brakes all already installed. There are a few things you need to do to set it up, following the instructions provided.

Essentially, you need to attach the handlebars, front wheel, pedal and LCD display. The bike comes with the tools you need to do so, and we find that this is actually a fun (and exciting) part of having a bike arrive, as you get to know the parts and how it fits together before you jump on and take it for a ride.

You can follow the instructions in the booklet that comes with the bike, or head over to their series of videos that show you how to assemble the bike, step by step.

Range of bags, panniers and accessories

Another great differentiator for Sixthreezero bikes is all the different bags, panniers and accessories you can choose from to customize your bike.

These include baskets, bells, locks, lights and child seats (check out this page on their website for the full list).

The accessories I chose to come with my bike are the Rear Rack Bag and the Frame Mount Bag, which comes with a clear cell phone pocket.

These are great as I don’t need to carry a handbag when riding my bike, I can stash whatever I need in one of these bags.

What’s it like riding this electric bike

This is a fun bike to ride! It’s very easy to jump on and get used to. This is especially true because of the step-through frame meaning you don’t have a high cross-bar to lift your leg over to hop on.

It’s also designed to have a comfortable riding position that may be better for people who experience back pain.

One of the things I love about electric bikes is that if you don’t intend on doing much pedaling, you can set them up in a very relaxed riding position like you see me in the photos throughout this review.

I like to drop the saddle so it’s easy to sit on with my feet on the ground. This riding position would not be efficient (or good for your knees) if you had to do all the pedaling, but I like it for cruising around.

This also provides stability if you’re getting used to the bike and the weight distribution (with the battery being at the back) when stationary and getting on and off.

To get in a better position to pedal, I just raise the saddle. The handlebars are at a comfortable height, with little stretch involved to reach them or the brakes.

SixThreeZero Bike Review Trail and Kale web wm 20

When it comes to stopping and parking, you can switch it off (using the key), and put down the kick-stand (like all e-bikes we’ve tested, locking it turns off the electric motor, but the bike can still be moved or ridden, so never leave it somewhere unlocked (or even locked) and unattended if there’s a risk of it being taken).

Where to buy Sixthreezero bikes

This particular model of women’s electric bike costs $1,999 at full retail price. For the non-electric version of the Ride In The Park bike, you’re looking at $649.

While you may find certain Sixthreezero bike models in retailers, the best place to buy one of their bikes – and especially the electric bikes and the full range of accessories – is directly from the company on their website.

This also means you can take advantage of the bike size fit-quiz and any current deals or offers they have on.

Sixthreezero offers free shipping Nationwide in the US as well as a ‘365 day test ride’, which means exactly what it says – you can return the bike to them, at their cost, if it’s not for you.
