Re: best conversion kit

AFAIK Electic Bike Conversions motors are 250w. I thought they should be ok without and strengthening. Happens I have steel forks. Steel forks are ideal for 250w so no Torque arms are needed, just make sure axle nuts are nice and tight. Two main reasons for T/A's is to prevent axle rotation in soft...

Re: Add-on e-bike conversion kit - Swytch or eBay kit?

I got very frustrated with Panda after buying a kit a couple of years ago, mismatched connectors, a battery that was entirely unsuited to my application (which I had discussed extensively by email beforehand), and the charger stopped working shortly after purchase. They were very prompt in replying...

Re: Going Tubeless - What Size Tape??

I have had success with tape a bit wider than the rim inner. It spreads up the walls at touch. If you are looking at "proper" tubeless tape you can buy similar stuff from ebay for much less. Look for yellow Tesa tape in 10m rolls. Tesa tape worked well for me on my Arkose when converted t...

Re: best conversion kit

Hubs shouldn't be fitted to front forks unless they are steel, some ali D/O's will eventually crack/snap due to rotation torque. Rockshok's are poor for fitting the D/O's are thin and fragile, Suntour's are better as they are quite meaty and thick. All ali forks with a hub should have torque arms fi...

Re: Crank drive query

With Bafang mid drive or any other clones like Mxus , Akm or even the tsdz you are limited to about 32t as the smallest ring before it interferes with the internal drive gear cover and you can use/fit a double with an adapter.

Because of the safety aspect?

Doesn't the camera shake like hell if it's frame-mounted?


The camera does rattle /vibrate a bit on it's fixing though pic wise doesn't show up to badly on the replay's.

Re: Replacement battery for e-bike (different voltage and Amp hours), will it work?

You can use 48v with a 36v motor if you know the voltage of the main in rush capacitor (which means opening the controller to look). A lot of 36v controllers only have a 50v rated cap so it will blow if use hook up 48v (54.6v fully charged), 48v volt capable controllers have a 63v in rush capacitor....

Re: Replacement battery for e-bike (different voltage and Amp hours), will it work?

if your ebike is a 36v then run a 36v batery. its a no branier. your motor may or may not take 48v but unless you have the motor spec why risk it. again you control box may or may not take 48v, and again unless you have the spec why risk it. so to the battery in your link, i wond first how someone ...

Re: Do E-bike riders get more exercise than regular cyclists ?

If leaving a battery for some time often over winter as some don't venture out much then leave the battery at approx. 38v a storage charge. Once a month check the voltage to make sure it hasn't drained any voltage. The issue with lithium batteries is no one who sells them actually know how to look a...

Grandad wrote:My understanding of this explanation is that after a ride it's better to leave recharging the battery until immediately before the next ride. This assumes that it has not completely discharged on the ride.

Is this correct?


Yes.

Re: Do E-bike riders get more exercise than regular cyclists ?

Just seen this reply - can I ask a couple of questions that have been interesting me as a keen ebiker! how long is defined as ‘not in use’ re batteries, and is there a practical/accurate way to check charge % level? I tend to class as not in use more then a couple of days, a fully charged battery l...

Re: Do E-bike riders get more exercise than regular cyclists ?

Going low is ok for a range finder test but generally will start to stress the battery if done regularly, it is ok as an occassional get me home if you happen to end up on along ride. The real damage that can occur is when voltage sag comes in to play and cuts power, if you wait sag will rebound the...

yes he did say 48v. 15ah battery then. is that more or less than normal for a pedelec? The box under the seat is very large, I thought there might be a car battery there, but he said was a lithium battery 15ah is pretty normal for 36v systems on pedelecs, though 48v/15ah tend to be a lot larger and...

Re: When is an Ebike not an Ebike?

In all aspects it is likely illegal and as stodd has said certainly doesn't come with in mobility laws. The hub is probably a gearless Direct Drive hub so likely 500 or 1000w, the battery will be 720wh but at what voltage. 48v possibly. He wasnt an invalid just a normal bloke He seemed to say had 3...
