First ride today after riding a cyrusher ovia

First ride today after riding a cyrusher ovia{condence sensor} Pleased to find my blue rumble is equipped with both sensors, will do a run with the torq sensor for a fell charge and note the distance covered, then do the same with the cadence sensor and compare distance compare and type of ride. The rumble is very maneuverable with an excellent steering lock. Found i only needed assist 1 and 2 with the full use of the gears that,s on flat terrain and a couple of hills. Very pleased as is the wife who has managed 40+ miles to a charge.

Nice little ride

It's very smooth so far, and surprisingly quiet. I've gone for 2 short rides, so will need more time with it, but the build quality is good. I like the folding handlebars as well. Lovely colour, smooth ride, and great price. The horn is super loud as well, and a nice touch.

Amazing 🤩

Getting this on discount + accessories like a phone holder, picnic mat, and other things for <£1000 for a very put together e-bike is just 😮‍💨

It has a rear rack already built on, ready to attach anything you might want to - like a basket or I’m considering a rear seat! I am in no way shape or form disappointed and so, so pleased with this beast. The UK laws just need to relax the speed limits and this would be a true canon!!

My next bike will also be Cyrusher, I’m eyeing the quest 😌 All in due time

Over the hills and far away

I have been looking and saving up for a while now, Trying to decide what bike has the power to get me up and down hills...This bike looks to be the best offerings for under £900, My first test ride proved that this was a good choice. I have built e-bikes with conversion kits previously and could only get the torque I required from 1000watt hubs....

Cryruser Rumble 2

I have had my Cryruser Rumble 2 for about 7 months now the reason I bought it was because I have bad health problems and to tell you the truth I wish I had bought one years ago so easy to ride and it takes a lot of the hard work out of ride in a bike except workmanship and I think I have only had it on charge for about 2 times and done over 100 miles.

A Bike for every Pot Hole..

Well this is it.. The RUMBLE 2 is the only way forward. . This bike has saved me form a bad accident many times. Due to its suspension. And fat 20. X 4 inch. Tyres. . They are not going to repair these terrible death traps for cyclist. So. The best answer is a. RUMBLE 2 e bike.. . BEST Value for money. And a safe ride..
You know this is the way forward.. . So glad I've got my Rumble mk.2..

Cyrusher Rumble 2.0

Велосипед просто чудо. Быстро разгоняется и не надо постоянно переключаться, особенно в гору. Очень стабильный, надёжный, лёгкий в управлении. Батареи хватает приблизительно на 75 км(при моём весе 75 кг + 10 кг полезного груза). Лак на велосипеде идеально смотрится и легко можно ухаживать просто протереть сухой тряпкой. Тормоза мощные, свет очень далеко бьёт даже в туман метров на 50. Всем рекомендую кто желает безопасной и комфортной поездки.

Top notch! Almost perfect! But...

Due to its success, we had to wait a while to receive our two Rumble 2.0s, but we had been warned.

Delivery was fine, despite one of the boxes not being closed, but no parts were missing.

Assembly was relatively simple for a DIY enthusiast, even if the instructions could have been more precise.

After almost 100km of use with only one full recharge since delivery, the Rumble 2.0 lives up to its promises: daily trips with gradients between 7% and 10%, in assistance mode 2 or even 3, I can cover between 45 and 50km.

Installing the accelerator is really simple, even if the cord is a little short. But the feeling and comfort it provides are great!!!

The bike is almost easily customizable: installation of a front basket, addition of a child seat (from another supplier because my son is too big for the one sold by the brand), addition of a trailer hitch. It's perfect!
Negative point: there are no footrests for rectangular tube frames, so it's not easy to adapt the ones I bought. If you have a product, I'm interested!

Now for two or three less cool points.
First, there's a particularly unpleasant noise coming from the left pedal (squeaking). I haven't looked into it yet, but it's something to keep an eye on.
Next, the part that secures the bike inside the frame slams against it with every bump... eventually it will break.
Finally, the last point is that comes up repeatedly in reviews: the saddle is not at all comfortable for longer rides (family outings, etc.). We had to add a saddle cushion to relieve pressure on the rear.

To sum up: these are our first electric bikes and we are not disappointed at all!!! Despite the negative points that I will mention to customer service, we are very satisfied with our purchases.
As for customer service, you are brilliant and business-minded! Nothing to say about that, available, responsive, friendly! Thank you.

Stay tuned, but don't hesitate any longer! This bike is awesome!

Great Bike for the money

Had my Rumble 2 just over a week. Im more than happy with it my first experience of an e-bike and haven't ridden any form of bike since I was in my late 20's now in my late 50's the addition of electric assistance is a great help.
