Traction problem with Big Bear

Featured Replies

Anyone that is thinking of trying to lift it will be disappointed by the results.

 

That is part of the keep fit plan Rob! Not only do you get stronger legs but also stronger arms and shoulders! :) And imagine you don't need to lock it to anything, thieves can't just drive up, grab it and chuck it in the back of a van. Instant hernia! :cool: </tongue in cheek mode>

 

Seriously it isn't going to be any heavier than one of those hideous fat bike things.

True, and it's only an extra motor and associated bits.

 

Carrying a spare battery or a well-stuffed panniers on a standard Bear would weigh as much.

When the battery is in place and the bike is on it’s centre stand, the weight is exactly the same front and rear. It could be used as a set of scales. I don’t intend lifting it. I have a brand new ‘second bike’ ordered and on the way. Should be here Monday. A bike that i can easily fold, lift and transport when needed. It’s a [mention=18852]KwikFold[/mention] Xite 3.

So confident that nobody will attempt to carry it away i have fitted a frame lock. So much better than carrying around a chain or a D-lock. Just turn a key and done.

And most of the time i have a trailer securely attached. My Big Bear is now used as my cargo bike. Very handy now that our council have started charging for taking away garden waste which i have opted out of.

See you've sold it! That's unexpected after all that work, hope you're not unwell. Not enough power?

Thanks for asking. I have had to go back to driving a small car and carrying a tiny folder in the boot to get me to places where motor vehicles are not permitted. I did put Big Bear up for sale but unfortunately while it was listed, the motor changeover switch broke. Very annoying as it was a heavy duty 9 pin generator switch which cost me £25 but only worked a few times. So, i have now got my BB in bits and i am returning it to its original form. But it will be a rear wheel drive with Dutch style handlebars. It will be a very nice bike when i’ve done.

This is it! Now converted to rear wheel drive only and decluttered. It handles and rides beautifully. I doubt i will offer it for sale again. It’s still only done 580 miles. I keep my little Kwikfold Xite-3 permanently in my car. Works out great.3145B797-1A51-42BB-898E-19B4EAA57259.thumb.jpeg.679a352cb1b052c6f9332caa8f25ba63.jpeg
Marwood remove the unused 4.4kg front hub motor and it will be even better yet.

Thanks for the tip. I have considered doing this but the weight on the front stops me from pulling wheelies. I like to sit well back over the back wheel.

And, i’ve turned the hanlebar stem around so it’s nearer the back.

Anyhow, tell us, how was your all wheel drive beastie while it lasted?

Not all wheel drive. That would not be road legal. It was either front or rear and switchable. But i never used front wheel drive after fitting a rear wheel motor. The difference in traction, handling and ride is anazing. I would always recommend rear or crank drive.
