**Please note that information regarding the expected range on a single stock battery charge on one of our e-bikes is an estimate, not a guarantee. There are many factors that contribute to the actual, real-world range for an e-bike battery such as the age of the battery, temperature, level of assist, speed, payload, and terrain. Depending on these various conditions, it is possible to get less than the expected minimum range or greater than the expected maximum range.

Love the bikes

So far we are enjoying
The ride. Easy to learn! Power on the hills as w live on a very hilly island! Nice to be able to still get a workout and not feel run off the road on our narrow roads.

Love This Bike

Excellent quality all the way around. I’ve had 3 other e-bikes and this is the first one that I’ve made over some extremely inclined fire trails without having to stop and walk the bike. Happy with the purchase of my Classic Duo, great power and torque. Customer service has been excellent.

Love it!

What a beautiful bike!
It took me about 45 minutes to unbox, assemble and adjust the seat and handlebars. I've ridden it almost 100 miles in about a week with zero issues. Looking forward many more miles.

The Best e-Bike on the market

Let’s start with how much I love QuietKat.
They make great e-bikes. They are a local business here in Colorado, and I love to support our business community
I don’t own any of them, because the base model of the Biktrix Juggernaut is better in every way.
I have my own that I ride constantly, and I’ve recommended and helped customize my sister’s, Fiancée’s, and 4 friends’ purchases.

Everything about Biktrix that I’ve encountered has been a big win for the customers.

One of my friends was ready to send his back to the company when things kept going wrong, but the support people helped us figure out the problem, and he was back on track as soon as the parts arrived.

I’m really happy to recommend people to Biktrix, not just because they are great bikes, but because they still do the work to make the whole experience worthwhile.

Great All-Purpose Bike

The Classic Duo rocks! Despite its weight and 4” tires, this ebike is very nimble and, with nine gears on the hub, it’s easy to pedal on PAS 0 (which I did on a recent 5-mile ride.) The mid-drive motor is very torquey and zooms up any hill with ease. Where I live IS very hilly yet I rode 86 km on my first full battery charge.
