This time, I will lead with the conclusion. The Heybike Tyson is loaded with the entire e-bike options I may ever need, is a blast to trip, and may turn out to be unsafe to function at a second’s discover. The unit I reviewed had multiple build-quality situation that can’t be neglected, which is a disgrace, as a result of that is additionally one of the enjoyable electrical bikes I’ve ever ridden. In case you simply needed to know if the Heybike Tyson is price shopping for, you have acquired your reply and may shut this tab. If you’d like the main points, learn on.
Priced at $1,699, the Class 3 Tyson is Heybike’s folding e-bike. Constructed with a magnesium body and painted vivid inexperienced, the Tyson’s scooter-like handlebars, mountain-bike-like suspension, and fats knobby tires lead to a trip that appears equal elements goofy, charming, and rugged. Able to carrying as much as 400 lbs (163 kg) of rider and cargo, the Tyson sports activities a twin hydraulic suspension to clean out the tough spots on the pavement. It has the identical Shimano seven-speed groupset and hydraulic disc brakes you may see on most e-bikes.

The Tyson appears to be like extra like an electrical moped than anything. It has a headlight, taillight, flip alerts, and even a horn that does a satisfactory imitation of the Roadrunner proper earlier than he is about to clown the coyote. It is powered by a 750 W motor and a 48V 15 Ah battery that may cost absolutely in 4 to 5 hours. Sadly, you may by no means fairly know the way a lot battery life you even have when you begin driving—extra on that, later.
Not fairly 99 issues, however…

At 77 lb (35 kg), the Tyson is a beefy bike. I put it collectively on my own, however some assist would have been welcomed, particularly when it got here to seating the tires and adjusting the stem. As is customary, Heybike contains the entire instruments wanted for meeting, and I discovered the directions are clear and straightforward to comply with.

Securing the wheels to the body is finished with a nut-and-bolt combo, and Heybike gives plastic covers to guard this combo from the weather, however they’ve an unlucky behavior of popping off the bike. However the greatest ache level throughout meeting was the brakes. It is by no means uncommon to should align the disc brakes after constructing an e-bike. What’s uncommon is to should do it a number of instances—and reseat the wheel—solely to appreciate that the disc itself is barely warped. Over my time with the bike, I’d sometimes be greeted by horrible screeching when making use of the brakes at greater speeds.

Aligning the handlebar-stem combo and entrance wheel was additionally robust as a result of foldable nature of the Tyson. In principle, it is easy: line the stem and handlebars up with the entrance wheel, fold down the stem to show a hex socket, and tighten it with a No. 10 hex key. Then tighten the hex nuts on the base of the stem. In actuality, folding down the stem can throw the alignment off simply sufficient to note. After which you should watch out to not contact the stem whereas utilizing the hex key. It took me a couple of tries to get the handlebar and entrance wheel lined up.
This results in the Tyson’s massive purple flag: The wheel-handlebar alignment can get out of whack very simply. After one journey, I seen that the alignment was barely off. So I braced the entrance wheel between my legs and adjusted the handlebar about an inch. The subsequent time I rode it, the steering grew to become looser and looser to the purpose the place the handlebars may not steer the bike. Fortunately, I used to be solely a few blocks from dwelling when this occurred, so the stroll dwelling wasn’t as dangerous because it may have been. The tighter the hex nut is, the much less probably alignment points are, however I have never been in a position to keep away from handlebar/wheel misalignments irrespective of how a lot torque I apply.
