Never arrived

Reason, I never ordered anything 14 days ago. I think your inventory/sales system is smoking strong ganja.
I do love my 2024 Juggs.

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.

Juggernaut Classic Duo: First Time eBike Purchase

I bought a Juggernaut Classic Duo after as my first eBike after a fairly comprehensive review of the market. I chose the bike based on the reputation of the brand for providing excellent customer support and my assessment that its bikes provide higher end components and superior performance features for the best value, especially for mid drive eBikes. As I planned to ride mostly in a mountainous area of Arizona, my research indicated that a mid drive was my best option. I couldn’t be more pleased with my choice! The bike is a quality piece of kit. It has easily accommodated 1600’ elevation changes over my favorite 25 mile loop using only 50% of the battery while leaving my 71 year old legs ready for another 50 miles. As a long time motorcyclist, the bike’s handling, stopping power and surprising quickness evoke the same feelings that made me fall in love with motorcycle riding. Well done Biktrix!

Amazing Bike!

From the get go, it was a pleasure dealing with biktrix. I reached out to their customer service team to clarify a couple of things prior to making my purchase. They were extremely friendly and knowledgeable. I placed my order online and in just over a week, I had the Juggernaut Classic Duo Electric Blue step-over in my living room. Assembly was a breeze (I have years of experience tooling on road bikes and mountain bikes) so it went together with no complications. For those that may be a little overwhelmed, Biktrix has really useful guides and manuals available online + videos to help simplify the process. The fit and finish of the bike is top notch. It is very well designed, however a little on the heavy side but to be expected with such a beast. I have not had much saddle time as of yet, but from what I have experienced the component package shifts smoothly, the brakes are well suited to this bike and the motor has plenty of power to spare. The Bafang DPC-18 display is very user friendly and provided all kinds of data right at your fingertip. I did upgrade the seat post to a short travel Thudbuster from their store and added the accessory mount which is a real necessity if you want to add a water bottle holder and cell phone mount. Overall, it is a large investment but well worth every penny I spent. I look forward to many years of outdoor adventure on my new ride and at the same time feel great about supporting a Canadian company. I did spend a significant amount of time researching other products/manufactures out there but kept coming back to Biktrix. So glad I did! What are you waiting for? Order yours today. You will not be disappointed.

Good Mid Drive Ebike

I currently have 6 Ebikes: Rad Rovers from Rad Power Bikes and All Terrain from M2S Bikes. Both brands are hub drive. I'm in the process of changing over to mid drive because of rear flats being easier to manage and more torque from a 750W Bafang motor (120 NM compared to 80)
I have 400 miles on the Juggernaut. After a few issues with the original DPN cassette bending easily, front Kenda tire defective and brakes hard to break in (noise when braking hard for long dissents). Biktrix did send replacement parts to fix the issues except the brakes and rotors. I replaced the rotors with Galfer Wave (2.00mm rotor thickness) and better brake pads. I also removed the fenders, rear rack and lights. Replaced lights with battery powered Fenix BC30R 1600 Lumen front and 200 lumen rear light. Everything is working perfect.
My only complaint is the bike is too heavy and would prefer a Torque Sensor over the Cadence Sensor it comes with.

Love it!

Before buying an electric bike, I did lots of research and decided to purchase one from Biktrix. So far Im extremely happy with my purchase! Its powerful, comfortable to ride, and is everything I wanted in an electric bike. I would highly recommend Biktrix to anyone interested in purchasing an electric bike.

Well built bike with quality components. The pedal assist is responsive and the ride is very comfortable. The speed achieved on assist and with the non assist throttle is amazing. Overall a great bike for paved and gravel roads!

NO OWNERS MANUAL

ONE BATTERY CAME DOA AND YOU WOULD THINK SOMETHING YOU PAID 3700 FOR WOULD COME WITH A OWNERS MANUAL. I WAS HOPING FOR A SMOTH SET-UP BUT WITH NO PRINTED MANUAL IT IS A JOKE. THE ONLINE INSTRUCTIONS SUCK AND EXPLAIN ABSOLUTELY NOTHING IN DETAIL. I HAVE BOUGHT OTHER EBIKES AND THE MANUAL FOR THE BATTERY AND CHARGER WAS OVER 100 PAGES AND ANOTHER 50 FOR THE MOTOR.

Juggernaut classic duo step-over

I have not been able to test the bike because there is an error in the e-bike panel. I have been unable to speak to a representative from the company to assist me in resolving the problem. The e-bike did not include a manual and it was not practical to follow instructions on-line. In addition, I purchased additional lights and installing the additional bike parts has been challenging. It would have been a lot easier to get the bike all ready assembled, tested, and validated. At the moment, I need technical support to get back to me so that I complete the e-bike assembly and can be able to ride the bike and provide a better feedback on the bike performance.

Great bike

Loving the juggernaut classic duo. Got the bike a couple of weeks ago and have been putting some miles in it. Rides great, climbs hills easily, and battery life is good so far. Also, I can’t say enough about the customer support. Had a few minor issues after a few days of riding, kickstand lost a piece and the battery lock came loose. Reached out to biktrix and literally had replacement parts 2 days later. I would buy from these guys again in a heartbeat.

Great packaging but

I finslly got my bike after 15 days(because of Purolator)
The packaging was good but it arrived with 2 spot of chipped paint parallel on the front fork. I know it wasnt when i unpacked it because it was on my wood floor on a carpet and it couldnt have been during shipping because the box was intact. That only leaves the factory/warehouse as a possibility. The fenders are high quality, screen's nice, i havent had much change to ride because of the ice and the fact that i dont have studded tyres for this bike yet but everything seems good on that part. I'm probavly going to upgrade the front light.
