Any cheap full suspension mountain bike not from wal-mart is about 2k. This thing has a motor and a decent size battery pack. Even the 750w bafang BBS-02 kit and lipo batteries from Hobbyking are around $700, $750 with charger. If you got a brand new full suspension bike for the kit you will end up over what this costs. This is with the 3kW motor and not a 750w.
That being said, I couldn't get away with this bike on the mt. bike trails. Looks too much like a motorcycle. I do like to take sharp turns using the pedals on my bike to shift my weight and actually enjoy using my own muscles to help the bike. That adds to the entertainment of it all. Lastly the option of bigger tires would help the bike. The video looks like he's riding a pit bike built for a ten year old.
I do hope they make their goal on kickstarter, but doesn't look too promising right now.
I'd like a bike from BZHwindtalker, but I don't think he'd sell one for this price.

I know nothing about electric bikes so I am really interested in what all of you experts are saying. I know that most are really happy with the kid's bikes but I don't have a young child. Thanks for all the feedback.

Tench wrote:I don't like the swing arm/drive sprocket relationship either, it seems the chain tension is at its tightest with the suspension fully extended creating massive slack under full compression, I would have thought it better positioned to be at the point it sags to with a rider on or in the middle of the travel to minimise the extent of slack at either suspension extreme, also the large distance between motor and pivot point exaggerates the large variation in chain tension throughout the suspension travel. done properly it wouldn't need a tensioner.
It strikes me that this is somebodies first attempt at designing a long suspension travel chain drive bike. Also as more weight acts on the suspension the pivot drops further below the chain run so the motors power will try to lift the back wheel making the suspension squat further when under power, this effect is also exaggerated by the large distance between motor and pivot.
Looking at the frame around the motor the tubes appear parallel so it would be a simple job to locate the motor a little further back, this would also have the benefit of placing the pivot slightly above the sprocket centre line moving the chains tightest spot to when there is some load on the suspension reducing both the above problems that have been designed into this chassis.
I would consider this far too important to compromise for the ability to put a different motor in which would also have the same drive line traits.
Its a grand looking bike! but could be designed better.

Why does a smaller/lighter motor than the gas equivalent still need to be mounted in that empty frame space? It feels like companies are simply taking the same designs and only swapping parts.
Not an engineer, just curious
i don't think the extra 3kW motor power will drain the battery or reduce range significantly..ilovehotshot wrote:Since the Trex is not going to be here until 2015, I am going to order a Free-Rider. Now I need to decide if I should order the Free-Rider $1999 ( 2kW motor) or the Free-Rider Race $2599 ( 3kW motor). I personally don't need the extra power but when the Trex comes in I will probably want to sell the Free-Rider. So I need it to be desirable for resale. Could I get some opinions. Also will the stronger motor drain the battery faster or only if the extra power is used. Thanks.
