Hello all! I built my bike about 4 weeks ago and everything was going well so far. I used this kit (the 48v 1500w model): https://www.aliexpress.com/item/1005003495298236.html?spm=a2g0o.order_list.0.0.2f351802lhgfzN However, the motor has decided it now wants to go backwards! I presumed it could have been a problem with the throttle wiring as I'd recently changed to a thumb throttle, so I wired the grip throttle back on but it still has the same problem. I checked the PAS, so I put it into PAS only mode, and it still has the same problem. It was all working fine and then one day, it decided to go in reverse! Is there something silly I'm missing here? Images attached, video below

Darn! Strange that its damaged. I didn't apply any excessive pressure to it when tightening the handlebar. Bike has never been dropped or bashed (yet!). I'll contact Andy at Woosh and see how much they are. Will probably wait until after Christmas when funds have been replenished. Thanks all.

Thanks Trex, once again! I will give it a go tonight

Hi all, Woosh Big Bear rider here. Riding to work today I noticed my handlebars were a little loose so I pulled over and tightened them up. After which my throttle has lost a bit of its springiness. When I engage the throttle (pulling it towards me) it still works fine, but doesn't feel the same and it doesn't snap all the way back into position. Also, when I push the throttle away from me all the way, it engages slightly and the motor seems to receive about 10%-20% power. Which can be quite dangerous if standing still at traffic lights and I apply some pressure forwards on accident. Basically, my question is, is this an easy fix? How would I go about rectifying this issue? crE

Andy says they are 8mm. Hopefully third time lucky!

Those attaching bolts arrived but they are way too small

:o really? Where would I find such a thing??

I took it to my LBS but they said they didn't have anything and couldn't find anything on the net. The fork is top gun: http://wooshbikes.co.uk/2014/bigbear/bigbear-6-800.jpg

Ahhh. I took it for a test ride and it works fine. No bumpiness or anything. Any problems if it is actually the wrong tube? The one that was in there originally looked the same size when compared

Hi all I am wanting to install V brakes on the front of my woosh big bear. They aren't a standard fitting so I was told to get an m10 thread boss so I bought these http://m.ebay.co.uk/itm/200951489567?limghlpsr=true&hlpv=2&ops=true&viphx=1&hlpht=true&lpid=108&chn=ps&device=m&adtype=pla&crdt=0&ff3=1&ff11=ICEP3.0.0-L&ff12=67&ff13=80&ff14=108&ff19=0#vi_details They are slightly too big and won't screw in. Am I going wrong somewhere.?

Well. I fitted it anyway. And it worked fine

No not patronising. I'm pretty new to this. I put the new pads on and they work a dream. Put pennies between the pads and the rim. Pulled it tight and tightened the brake cable. A bit of adjustment on the springs and it's all good. For now

Oh and yes. I did move the cable. Kept doing it and doing it. It was either full lock or no contact

Thanks guys. The new pads arrive today. Thanks trex on the wilko tip. When I fit them I will take photos. And will clean my rims regularly

Really? I was adjusting them with my allen key and even when perfectly aligned they hardly gripped... am I doing something wrong?

It would bother me. There's a couple of times I'd have rammed into the back of a car without it!

Looks like I'll just keep buying a regular supply of pads and change them every month or so. At 1.99 each that's not too bad. Cheaper than petrol!

Thanks trex. You mean prolonging the life of the rims as apposed to pads? Or both?

Good idea. I do 20 miles a day, 5 times a week. With a backpack with various bits in it. 11st 3 lbs. Looks like I'll be asking for a bag of brake pads for Christmas! Am going to get some V brakes fitted to the front too. So even more pads will be needed. I just don't get on with mechanical discs

Wow jamesw. Maybe we are regular brakers!

Here they are. Dead! http://tapatalk.imageshack.com/v2/14/11/24/62a298117786fbca8b21abdec5e3b2c4.jpghttp://tapatalk.imageshack.com/v2/14/11/24/9e15ab880b655912c51aaddf4ffe96eb.jpg

I will check

Done 300 or so miles on my big bear. Normal commuting. Sort of hilly. The back v pads are shot. They look very worn (unfortunately can't provide a photo now) no braking power. Is this normal? If not. Is there anything in terms of the way they're setup that could be causing excess wear?

Thanks trex. Very useful
