Gsm vs bbs01

[KirstinS]

Woosh are expecting the kits in on Friday/Saturday I was advised today

Plus a a bit of turnaround time and we can all hope for delivery sometime pretty soon. !


I will do a build thread separately.

Though as I've never fitted a bbsxx it would be great if someone who had both could post, in due course, about any key differences they discover (outside headline spec and this thread)

To go into setting mode, you double tap the on/off (middle) button of the LCD.

Is the GSM adjustable re the cut off speed?

 

[trex]

yes. You double tap the on/off button to go to settings, tap to the maxs (max speed), adjust with + and -, long press on/off to save. Maximum set speed is 57km/h. Very similar to the King Meter.

 

[willywombat]

57km/h ..pah ...not worth having
seriously though might be nice to up it from standard by a few km/h occasionally

 

[KirstinS]

Wife called to say mine arrived just now

If any one has any fitting tips much appreciated. Cannot be as easy as the manual shows!

the hardest job is to undo the old bottom bracket. You may need to whack the spanner a bit with a mallet to loosen an old BB.
Start with undoing the non-drive side (left cup first), then the right side (chain side). On the chain side, the cup is left hand threaded. If in doubt, always turn your spanner in the direction of pedalling to undo the cups.
Make sure there is no lump of excess weld inside the shell where the tubes join together. If there is, and it's rare on good bikes, you may have to spend 15 minutes sanding any lump off.
Once the inside of the shell is nice and clean, the kit will go in easy peasy. I always put a bit of grease inside the shell and around the BB axle.

Can the throttle cable and brake cables be cut off the wiring harness without causing a short or is there an LCD to controller only cable option?

Hi trex, thanks - that job is done by my lbs as they took 5 mins and charged 7 quid. The tools alone were going to cost me about 35 quid

Money well spent it seems !

£7 - how do these guys make a living? you should post his name - members of the forum, take notice.

If you have a Shimano UNxx bottom bracket, you'll need this £5 tool set:

You can, but switch off first.

you only need to connect the battery and LCD to get the GSM going in pedelec mode.

1. connect the battery: connect the tail with bullet crimps to the battery first, red wire to battery +, black wire to battery -. When done, line up the arrows on the battery connectors and push the two connectors together until snugly fit.
2. connect the trunk cable to the GSM then connect the 6-pin male (green) LCD connector to the 6-pin female (black) on the handlebars end of the trunk cable.
3. Turn on the LCD
4. rotate the crank arms, your GSM should spin up.
There are 9 assist levels programmed into the LCD.

Is this the first generation of the GSM ?..I'm interested in buying either this or the BBS01 but always a little wary of stuff that's new to the market ( don't like to be a beta tester !)

28.50 € (20 minute job flat rate) just around the corner... I guess that the easy ones help pay for the BB removal made in hell that takes him an hour. The other LBS would probably do it for me for 5€ we have more of a bartering relationship...

A good 35-45 € general purpose tool kit (bikediscount.de) will always be handy now that you have a pedelec with a kit mounted. Mine has long since paid for itself.

it's the 2nd generation. I tested the first generation about a year ago, made a couple of suggestions because I have the BBS01 18A 350W. The main suggestion was to have a 250W motor but with 18A built in controller so that the motor can be road legal on kits. Back then, the controller was external so it did not matter. My current suggestion is to make the built in controller compatible with the King Meter LCD. At present, if you want to use the King Meter LCD, you still have to use external Lishui controllers. The built in controller is compatible with APT and KT LCDs.

Can you change the chainwheel on these GSM CD's ?
46T is too low geared for me.

 

[trex]

As far as I know, the GSM can use the same chainrings for BBS01/BBS02.
You can buy from the usual sources such as http://www.greenbikekit.com/accessories.html/

Actually it was the local big giant store. The others were too busy. They did it on the spot ! It was actually 7.50 to be fair
