Heybike Helio U - White

Heybike Helio U at GOfatbike

The Heybike Helio U is a lightweight city bike with large 28-inch wheels, designed for those who want to move smoothly and calmly through the streets. A torque sensor ensures the motor assists as soon as you start pedaling, giving a natural cycling feel. You step on low, and with a light frame, you can easily lift and steer the bike. In this explanation, we go through what the Helio U can do, its strengths, and what to watch out for before you choose.

Frame, entry, and comfort

The aluminum frame has a low step-through and weighs around 20 kg, so you can get on and off in one motion, and lifting requires little effort. The 28-inch wheels with Chaoyang 700C x 40C tires roll lightly and keep you stable in corners and on the road. You sit upright, with a good view of traffic, and you can adjust the saddle to your height. The frame supports up to 125 kg, plenty for you plus a full bag. Larger wheels roll smoothly and maintain their speed, making the ride calm and smooth.

Range and battery

The 36V 10Ah lithium battery, totaling 360 Wh, allows for multiple rides in a row. How far you go depends on your weight, the wind, the level of assistance, and how often you accelerate, so consider a margin rather than a fixed number. Riding steadily in a lower assist mode will get you noticeably further than in the highest mode. The battery fully charges in a few hours, so you can charge it in the evening and start fresh in the morning. With IPX5 protection, a rain shower won’t affect the technology.

Motor, gears, and regulations

The 250W Galaxy rear hub motor delivers 45 Nm of torque and pulls you smoothly thanks to the torque sensor as soon as you pedal. Assistance goes up to 25 km/h, without a throttle, so it remains a natural cycling experience: the harder you pedal, the more the motor assists. This means the Helio U counts as a regular electric bike: no license, registration, or helmet required. With the Shimano Tourney 7-speed, you can choose the right gear for hills or pace. We advise against tuning the bike, as that would put it outside its legal category, the brakes aren’t designed for that, and your warranty could be voided.

Brakes, lighting, and equipment

You brake with hydraulic disc brakes, which provide short, controlled stopping distances, even in the rain, and require little hand force. LED lights at the front and rear keep you visible in the dark and provide your own view of the road. The torque sensor ensures smooth acceleration, and the large wheels offer a steady roll. Furthermore, the bike remains straightforward to use, without complicated technology. If you want a lock, bags, or fenders, separate accessories can be added.

Who is this e-bike for

The Helio U suits those looking for a light, comfortable city bike with a natural pedaling feel and large wheels that roll smoothly. Great for commuting, shopping, or a ride around the city. To be honest: because of the 28-inch wheels, this is a somewhat larger bike than a compact 20-inch model, so it’s less handy for tight storage spaces or car trunks. If you prefer a calm, straight city ride with a full-sized, large wheel, this is a good choice. For taller people, the 28-inch wheels and spacious frame are often more comfortable than a small city model.
