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.

Rumble 2.0 blue

Overall, I am satisfied with the bike. It is very easy to handle, and the torque sensor has its advantages, but the user has to put in some effort to move forward....
The battery life is so impressive that I wonder if there is a problem with the display... I will have to check this over time.
