Cyclotricity bottle battery dimentions

[Agelos]

Hello from Athens Greece!

My name is Agelos and I love cycling! I am into road cycling for a long time and I also commute daily to work. Lately I decided that having a shower every morning in my office bathroom (it is hot in Athens now - imagine in the summer!) is not an option for me anymore, so I consider converting one of my rides into an electric one.

Basic info:
Commuting distance: less than 10 miles
Terrain: quite some uphill but not that steep - city centre (Athens)
Fittness level: good
I dont look for a moped, just some assistance to avoid sweat before office!

The bike is a 2012 GT Avalanche 1.0 and after some recearch in local dealers and the net, I think that the kit from Cyclotricity is a suitable option. The challenge in my case is the very limited space in the bike's triangle that prevents the installation of most batteries that come with the kits that are in the merket here. There is no dealer in Greece offering the Cyclotricity kit so I could not check it out. I wrote to the company but got no answer so far and after I checked this forum I decided that this is the place that I could find help. It seems that some of you guys have really grasped the issue of electric cycling - it is amazing I had no clue on this so exciting dimention of my favourite sport (and way of living...)

So, if someone can measure the dimentions of the bootle battery with the base and the necessary clearance to be removable from the base, I would really appreciated it since I need to order through the net and if it doesn't fit it would be a great dissapointment.

If it helps, I visited the local dealer of OXYDRIVE (yes, there is one in Athens, but the price is much higher) and the battery of this kit that looks very similar (maybe identical?) to the one in question fits my frame with less than 1/2 inch clearance - anything even slightly larger would not fit.

I hope I didn't tire you much, thanks in advance for your help and any other suggestions are more than welcomed.

The cyclotricity one is the the same, but the mount is a bit shorter because it doesn't have the controller in the base, but you have to unscrew the connector when you want to remove the battery.

The sideways mounting batteries are a lot better if you have limited space, plus you can get the much stronger 11.6aH one like that:

450Euros for that lot. You need to order a PAS, throttle and wheel-speed sensor too, so about 500 Euros total. Then there's any duty you have to pay

Thank you very much for your answer. Now I have more questions:
1.Is your proposed solution better than the cyclotricity one? (they answered that the battery is the same with the oxydrive)
2. If I go with the one that you propose is the motor compatible with the controller that fits in the battery base? I am a little confused cause the site does not give this controller as an option. I quote: "You can select S06P, S06S or LSW-675 controller for this motor.)
2. Any idea on the weight of these kits? (The oxydrive weights 6,5 Kilograms)

I dont want a heavy kit and extra components on my bike, thats why the oxydrive/cyclotricity kits appeal to me most.

The Oxydrive case is the same, but what's inside is much better cells. Also, the Oxydrive motor is a Dapu, which is light, strong and very free. On the surface these kits look the same, but the Oxydrive is better quality.

The controller I linked to is a S06S bottle battery version. It has the advantage that it fits in the battery case, but it's a bit tight to get all the connectors in. The disadvantage is that you can't increase the current by soldering the shunt because it's sealed.

The all-up weight of the BMSB kit would be about 5.5kg. It should be exactly the same as the Oxydrive. Maybe they've included the rim and spokes in the weight of the Oxtdrive. I'm only cobnsidering the weight of the motor, battery, controller, etc.

The battery in the BMSB kit is better. The battery has more capacity. There's a sine-wave controller with LCD (£100 option on the Cyclotricity kit). There's loads of options with the BMSB stuff. You can get different throttles and PAS sensors. It's not so plug-and-play as the other two kits, and neither do you get a guarantee/warranty.

Could this work?

since the controller is for 250W and the motor 350W? You see, I dont have a clue on the matter... I can't figure out the difference between the sine and square controllers...

My options are:
1. I spend 1040 euros and have my bike fitted with the OXYDrive kit in the local dealer with 1 year guarantee/warranty.
2. I buy he OXYDrive kit from their site for 880 euro and I fit it myself, or
3. I go with the BMSB solution which is almost half the price, but I have no warranty and I need to do the work myself (which I enjoy, but I am not 100% confident on doing it properly)

The Cyclotricity kit for 700 euros is the least favourable option after your post. I wouldn't go for lower quality and not that lower a price.

The So6P in that battery doesn't work very well with the Q100. The 350w is OK, but the motor needs a sensored controller.
