I have had my Fat Bear (B&W display version) since mid October...it arrived fully assembled in good shape. I did make sure all the fittings were tight and adjust the seat and handle bars. I also have a Lectric XP bike that I got in September. Except for the upgrades and the front and rear suspension, I have found the two bikes almost identical. However, the post sale customer service for the Rattan Fat Bear has been non-existent!
I too have a problem with the electronic controller. In throttle mode (no peddling), it works just fine. However, the PAS mode only seems to have one power level, regardless of the PAS setting; about 18MPH on a flat street. For instance, when going up a steep grade street, the Fat Bear e-bike will just make it with the throttle controlling the power. If I try to use the peddle to assist the motor in throttle mode, on the same hill, the motor will almost shut down (I can still hear it running) no matter what PS mode I am in (1-3). In comparison, my Lectric XP PAS modes work as they should and will allow me to use either PAS or throttle (or both) to get up the hill.
One other issue is the battery key on the Bear...it does not turn the power off (unless you remove the battery); it is always “on” regardless of the position. I guess I’m lucky it’s always on and not always off!
I have tried to contact Rattan many times over the past few weeks (via their email addresses as listed in the manual) with no reply. They have no phone support that I can find...just email addresses that they never reply. By contrast I have contacted Lectric (about getting a replacement inner tube) by email, with fast and excellent after-the-sales support! I did get an email from Rattan asking me to write a review for their WEB site! If I ever hear from their “service dept”, I’ll let you know....tomg
