Z4 Lite Lightweight Electric Bike

The Z4 Lite is the ultimate lightweight electric bike. Sporting a light foldable frame and a 350 watt motor, the Z4 Lite offers the perfect blend of power and portability. Plus, with 2.6” wide tires, a rear cargo rack, and other great features, the Z4 Lite is one of our most versatile rides.

Folding Frame

An easy-to-fold frame makes the Z4 Lite totally portable without the use of a bike rack. You can fit your e-bike in your car, in a closet, or even under your desk.

2.6” Wide Tires

Built with 20” by 2.6” wide tires that absorb the shock of bumpy roads and multiple terrains, the Z4 Lite is designed to be a reliable lightweight e-bike for all types of riders.

Pedal Assist and Throttle

The Z4 Lite’s pedal assist and throttle ensure that you’re in control of your ride. Choose between 5 different speed settings ranging from 7 to 20 mph, or use the throttle and skip the pedaling entirely.

Rear Storage Rack

From groceries to deliveries, the rear rack is perfect for carrying anything you can’t fit in your backpack.

Digital Display

A crisp digital display provides quick readouts on speed, battery life, pedal assist, headlight control, and more.

LED Headlight

The Z4 Lite’s bright LED headlight provides important visibility during early morning and late night rides.

Poorly made, bad customer service. I have had the bike less than 3 months and have already had several issues. The brakes began to fail, the pedals both cracked and had to be replaced, and the charger stopped working. Ordered a replacement charger from Go Trax 2 weeks ago and have not even recieved shipping information yet, have tried to call customer service and get put on hold until a reocrded message tells me no one can accept my call. Don’t buy this bike.

Rear Tire Issues

I bought the z4 lite in october 2024 for my son to get to work. he's had 3 flat tires since then. he rides on fairly smooth roads to work. it's not that the tubes are expensive because they aren't. it's the time it takes to install another one. i really wish i would've chosen another kind of bike.

Great bike, terrible instructions

The bike itself is wonderful, once you get it assembled. The instructions were so unclear that I had to look up reviews and find answers as to why I was missing a bolt to the front tire. I finally found one that said it was inside the plastic piece that was originally on the tire, to protect the disc brakes. I would’ve ended up calling the company and asking for a replacement part if I didn’t find this information online. The photos and descriptions on the instructions were awful and shipping was terribly slow!

Battery life is good.

The battery charges fairly quickly and is more than enough for my daily commute,but could be better for longer drives.

Awesome eBike!

After doing much research on ebikes, I finally made the decision to purchase the Go Trax Z4. The bike came in a box with assembly instructions that were easy to follow. It took me about 25 minutes to be up and running. The only thing I added was a handlebar mirror. I was pleasantly surprised by the level of power the different speeds offered. Charging the battery was simple, and with my usage, I was able to get about four days between charges. The bike is very comfortable and easy to ride. I purchased the bike almost one year ago. With that, I had one minor equipment issue. I contacted the company and received an immediate response. The customer service representative was great at addressing my problem. They sent a replacement part immediately as well as the support to install that part. I give this bike a 5-star rating. I will give the company’s customer support a 10-star rating for their responsiveness!

Feeling average

This is an average electric bike.There is nothing particularly noteworthy about it.The motor and battery are great,but I think the ride quality could be better.I think it would be better if they added padding to the seat.
