Our first e-bike we bought for fun local trail

Our first e-bike we bought for fun local trail rides. So far it's great, easy to assemble and feels good quality. Cyrusher kept me updated from order to delivery. Seriously considering a second Cyrusher for my son.

Bikes ok but arrived looking like a refurb

Bike work's as should but visually looks rough the finish is terrible and the battery doesn't fit flush when in the bike,I think I should of sent back when it arrived upsidedown down as the battery had been slapping in the frame ,but as a bike for getting blame from new abbey to Dumfries on the hilly farm tracks it's awesome I just wish it wasn't as scruffy looking but performance is amazing and comfortable I have spinal spondylosis and this bike has given me my independence back.👍

Be careful not good

I’m not satisfied with the bike at all. First, the bike arrived with the box damaged, and the bike itself had sustained damage — it had a lot of damage. Then the fender/mudguard kit also arrived and it didn’t fit properly, so I had to make some modifications to it myself. Also, I’ve only recently started using it, and the battery is extremely bad as well — I’ve only gone 42 miles total in gear 1, and the battery drains very quickly. Two battery bars on the odometer/display disappeared very fast, and when the bike’s battery actually ran out, the display showed that it still had two battery bars remaining. In my opinion, this is truly disrespectful to the buyer, and I am completely disappointed in your company and your low level of accountability. Whenever anyone asks me, I only ever recommend that they should not buy a bike from you under any circumstances.

E bikes Aura & Zenith

Wow what great fun these bikes are. We brought two bikes the Aura and Zenith, they arrived very fast and well packaged. Easy to assemble. The bikes are easy to use and great fun when out and about. The batteries are easy to remove and to charge. Using the User manual to understand the bikes was very handy as new e - bikes owners. Highly recommended and hours of fun. A great purchase and makes going out on for a bike ride a million times easier.

Love my bike,so far so good.

This Cyrusher Zenith fat tire ebike is an absolute game-changer! The chunky tires easily smooth out bumpy roads, uneven paths, and loose gravel, while the powerful motor makes hill climbs effortless. It’s incredibly stable, exceptionally comfortable, and simply a blast to ride anywhere.

Love My Zenith

Easy to build, very big E-Bike. Gorgeous colour with a great design. Looking forward to going places without taking my car and, fingers crossed, getting more exercise and, subsequently, getting fitter in the process!

Excellent multi purpose bike.

This is my second Zenith and I use it in a flat area of the UK. My other Zenith is for a mountainous area in Spain. The dual sensor means that the bike’s power can be utilised excellently across both terrains. The 52V rating means that the massive torque can be fully utilised. (A lot of competitors claim higher torque but do not have enough voltage to actually power the motor to that capacity.) I have not attempted any hills that the bike can’t handle, or on the flat cruise at top speed on very limited assist. I love this bike and quality and delivery was exceptional especially considering the price.

I had my first ride out today and was pleasantly surprised I'm a senior rider and I found this bike easy to get along with, delivery was fine and assembly was straight forward, so all in all I'm a satisfied cyclist.

First Ride

My first test ride was actually an 8 mile commute to work and the same back. Went so smoothly across hilly west Cornwall, arrived with plenty of oomph for a 12 hour shift. The pic is from the return ride in the evening, lights are excellent.

Great customer service!

Again very pleased with the service from Cyrusher, Glen was very helpful sorting out the issue I had and quickly resolved it by dispatched a replacement bike. First ride out this morning went well, no issues. Rides really well, very comfortable and plenty of power, could do with getting the mud guards not sure why they don’t sell them on there own without the rear rack, hopefully they will soon. All good thanks for the great customer service.

First Ride

Very pleased with the Zenith, fast delivery, straight forward assembly, I did snap one of the plastic shipping cap’s off in the front wheel hub, had to carefully drill it out, need to be mindful when removing, go easy. Was also confused as seem to have a spare connector on the wiring loom, but after seeing the same on a couple of YouTube videos, figure its for an accessory like a horn?. First ride out this morning was a pleasure, road, track, mud and gravel no problem, nice to have the two drive modes, cruse on the road and switched to torque off road. Very comfortable with the fat tyres even over large roods. Did eleven miles and one of the five battery charge lights went out. So to sum up so far very pleased with the bike and service from Cyrusher, lust need to clean it now, Cheers!

A monster of power and style: The Cyrusher Zenith

I want to share my immense satisfaction following the purchase of my Cyrusher Zenith. From the moment I received it, the experience was flawless: the delivery was fast, perfectly organized, and the package arrived in impeccable condition, a testament to the care taken during transport.

A design that commands respect:
I chose the dark gray finish, and the result is simply breathtaking. This matte gray, so deep it's almost black, gives the bike an aggressive, understated, and high-end look. Its double-bar frame isn't just aesthetically pleasing: it exudes robustness and unwavering solidity. It's a bike that doesn't go unnoticed and oozes quality craftsmanship.

Unparalleled motorization and technology:
The motor is the true heart of this machine. It delivers impressive power that gives the exhilarating feeling of being tireless. No matter the incline: it climbs them It tackles even the steepest hills with disconcerting ease.

The combination of the torque sensor and the pedal assist sensor is a technological masterstroke. The responsiveness is instantaneous and natural. Frankly, the power reserve is so vast that I ride almost exclusively on assistance levels 1 or 2 (out of 5), which speaks volumes about the phenomenal potential of this bike.

Versatility and safety:
Finally, a word about the tires: they are excellent. Whether on asphalt or more technical and varied terrain, the grip is total, offering a constant feeling of security and control.

In short, the Cyrusher Zenith is much more than just an electric bike; it's a high-performance and beautiful machine. I am absolutely delighted with my purchase and I recommend it without hesitation.

A huge thank you for this exceptional feedback and such kind compliments! 😊

We are absolutely delighted that your Cyrusher Zenith perfectly meets your expectations in terms of design, power, technology, and versatility. Your satisfaction is our greatest reward.

We wish you many enjoyable and safe rides, and thank you for your recommendation!

Sincerely,
The Cyrusher Team

I highly recommend it

I tested the new Zenith on the slopes of the Sierra Nevada, near Niguelas. I'm pushing it to its limits, and so far, it's responding perfectly to every request.

What a pleasure to ride this bike! Its climbing capabilities are truly excellent.

My father also bought one, and seeing a 79-year-old man comfortably riding the GR7 is priceless.

Thank you so much for this exceptional feedback! We are delighted that the Zenith lives up to your expectations
