Its 93.6Wh/module

There are different pricing depending on the model. Base model with one battery module is £269, fully upgraded unit with 3 modules is £369. The modules are made from 18650 cells, good for at least 2-3 years of fair use. Warranty is two years though and replacement only costs £45

One battery module gives about 10miles (16km) of pedal assisted riding. So the fully upgraded unit (with 3 modules) can go for up to 30miles(48km). Yes, base model comes with one battery module and you can buy and install up to two more modules by yourself. Modules are easy to install but are not designed to be "swapped on the go". After additional modules are installed the unit must be charged fully to equal the charge of battery modules. Yes the unit is rechargeable, it takes 45 minutes/module to recharge. Btw great questions guys !

It does, but you can expect a bit more noise than in the video above

We solve friction using three methods: 1. Integrated suppression system (200N pneumatic spring); 2. Special roller material with aluminum oxide particles (lifetime warranty); 3. Electronic anti-slip control (similar to ESC in cars); So we pretty much solved the "Achilles heel" of friction drives. The roller material is designed to conserve the tire as much as possible, but tire can wear off 10-20% faster. As for the sound - here's a a video of the old version being driven, the new one is even more silent due to better motor control. https://vimeo.com/70936744

Well yes, the portability and ease of installation has it's drawbacks. Rubbee is designed for people who often park their bikes outside for the whole day/night and want safely disconnect the e-part from the bike. Our customers also appreciate the fact that they can use Rubbee for daily commuting and remove it once they want to get some exercise on weekends the bike becomes a multipurpose vehicle, without adding much weight. Thanks for the feedback !

People who don't use them that much are happy to trade them for electric assist

What mudguard? Yes, you do have to remove the mudguard. But Rubbee catches most of the splashing on the bottom part of it.

d8veh, good questions ! Speed and power curves are according to the EN15194 regulations, up to 25km/h/250W. Unless You upgrade the unit to 3 battery modules, then You unlock the 350W/20mph US standard (selectable via app, can work on the EU standard too). The sensor is Bluetooth LowEnergy 4.2. with integrated accelerometer. It uses just two cable ties to clip on the crank. We do send an encrypted signal with double redundancy so no interference was detected in our R&D procedures.

Hi guys ! I've been on this forum a couple of years ago and thought to share some news with you. Not many of you know but I'm the guy who created the Rubbee friction drive And now we are introducing the latest flagship model, the Rubbee X. Regen braking, completely wireless, expandable battery modules. Here it is, what do you think? Would appreciate any feedback, do you like what you see? How about the features? It would be amazing to get the community feedback. Looking forward to hearing from you, thanks ! Gedas.

Hi Nealh, Yes, drilling out the inner diameter of the ring and screwing it onto the chain ring is one solution. But that requires a lot of DIY. I'm not afraid of it but isn't there a ready solution for installing the split magnet ring on the left side of the bike for those newer bb assemblies? There must be something.. Thanks for the idea though !

Hi d8veh, Yes, installing the pedelec sensor head would not be a problem. But what about the magnet ring that has to spin with the crank? The crank has to stay flush with the bearing casing (meaning there is no gap to insert the disk in between them). And the bearing case itself (the silver thingy) is stationary. Any thoughts on that? Thanks. Gedas.

Hi, thanks for the reply. But I'm not sure this will help. You see, in the picture above the "silver part" (the bearings assembly) is fixed to the frame and does not spin with the crank. So the magnet disc should be fixed somewhere on the crank itself. Any ideas? Thanks ! Gedas.

Hi guys, First post here, You are my only hope ! I'm not a newbie on the scene of pedelecs but I still have a question that stays unanswered for about half a year now. I've been using split pedelec sensor magnet discs for some time now and the are just great. But they only work with older square tapered bottom bracket assemblies. Maybe, just maybe, somebody here knows a magnet disc solution for newer bottom brackets that don't have the gap for the magnet to fit in? a magnet ring that could work on something like this: http://brimages.bikeboardmedia.netdna-cdn.com/wp-content/uploads/2010/02/externalbb.jpg Let me know if anyone has an idea on how to install a magnet on this thing. PLEASE ! Will be waiting for any feedback, thanks ! Gedas.
