What have you got?

Postby Joeblake » Fri May 21, 2010 8:59 pm

Okay,

First one.

Two converted Greenspeed electrikes with photovoltaic panels to keep the batteries charged.

Just looking on my favourite site, Gizmag, a collection of "possibles" (my own personal definition sub-500 watt motor with proper pedals and gears).

Although I can't find any definite power figures, for some strange reason I like this one.

Sorry don't have one but in the future one of these might be the go.

A couple of web site with the Green wheel bike and foreseeable high tech use in a smart city setting.

I have a Jamison Dakar Sports 26" MTB with aftermarket 200W EVS kit, comprising a 36V 200W (constant) rated Shenzou Bafang front hub motor, with 14AH 36V Ananda Controller & thumb throttle. With help from the Endless Sphere forum & Pedelec Forum http://www.pedelecs.co.uk/forum/ over time I have modded & upgraded my kit to suit my pedalling effort & tempo & required battery endurance, distance/time covered etc.

Hopefully this link shows a pic or two...

http://www.pedelecs.co.uk/forum/attachm ... mtb-4a.jpg
http://www.pedelecs.co.uk/forum/attachm ... mtb-5a.jpg

I have a 7.2V 18AH NiMh "booster" pack in the left rear pannier position, tools etc in the right pannier pocket. Headway 36V 10AH LiFePo4 pack in pannier bag on top of bike rack plus an EVS 36V 14AH Lipoly sitting snug in a custom holder I had made for the frame (bolts on to existing drink bottle mounts). Total system (2 x 36V in parallel + 7.2V in series) gives me 50V off the chargers & main working volts from 42-48V over 70+ km. A Cycle Analyst is on the handlebars to help constantly monitor the system.

This stock standard Bafang 200W (Aus legal) gear driven hub motor & controller easily takes the extra voltage I have added, since the controller limits the current to 14A no matter what the voltage is (up to around 55V safe). The controller caps are rated at 66V and no-one has had any problems at this voltage & current (so far). At the max main working volts of 48V the motor pulls around 680W (peak) without getting too hot. Totally stock (36V system only) the motor will still pull around 530W (peak) at 38V working. So, don't be too put off by the piddly little 200W Aus rating. That is a nominal (and conservative) CONSTANT output design figure. Trial & error testing by unrestricted US e-bikers have shown these motors can easily take up to 1,000W for short bursts and up to 400W (constant). They are over-engineered for their spec to allow for most eventualities... :) . I've covered almost 1,000km with this setup now and NO PROBS AT ALL.

The extra volts gives me approx. 5kph more top speed. With moderate pedal assist I can now achieve long rides on the flat at around 32kph ave. At 36V this drops back to 27kph ave. The parallel batts setup plus booster now gets me up to 100km :mrgreen:

Tyres are Serfas Drifter 26 x 2.0" (AT) 60PSI front, 70PSI rear (these tyres have built in puncture resistance), with additional thorn resistant tubes + Mr Tuffy liners. *Almost* bomb-proof. I previously had Specialized Armadillos 26 x 1.5" - ride was a bit too harsh for me at 85psi plus the much smaller circumference I found was reducing my top cruising speed by 2-3kph. The Drifters are much more comfortable on the road & trail and can handle the extra 4.5kg 36V parallel battery weight better too. I COULD gain a further 3kph by fitting some big circumference Maxxis Holy Rollers (26 x 2.4") I have that I used to use on trails, but they are sooo prone to punctures by thorns, glass slivers etc (even the widest Mr Tuffys are too narrow to fully protect them). I think they might be too much of a PITA!

I have a bit of a dud back (old damaged disc) and found the addition of aero bars an absolute godsend on longer rides. The setup I have allows an almost infinite variety of hand grip & arm rest positions which helps to relieve pressure points. I also found my back very much appreciated my arms and shoulders taking a bit of weight from time to time as well! They are a bit fiddly to set up to the perfect angle, balance, etc for you - takes numerous adjustments and test rides to find it, but once set, they are GREAT - I can easily hold +3kph on a long ride into a 15kph headwind compared to standard situp position - what a boon.

Cheers,

aj

Sorry, Jeff

Can't see your piccies. Need to register to view them.

Perhaps you can post them as images into your next post. (I think you need to have made 10 posts in order to put images in.)

Sounds good though.

Ah, that explains why I couldn't find the "upload pics" function then!

Oh well, only 8 post to go then you can see 'em all. :)

The gizmag.com/1811 picture looks fly. I really would love to use one of this.i don't know if is better than riding an ordinary bicycle but i sure know that i'm dying to try.Hope to get the chance one day...

I have a Wisper 706 .... and LOVING it!!! I thought my days of throwing a leg over a bike frame were well and truly a thing of the past (bicycle toured extensively in Australia and overseas years ago) but my e-bike has resurrected the passion. Why do I like it?? Firstly the design is great for some one whose back looks for an upright position. The gears are a dream. And, of course, having the option to get a boost up those hills is fantastic. In the short time that I have had my bike I have been surprised how little I actually need the e-boost if I work the gears accordingly. It's been great to zip in and out of the city and around the local area etc. While I feel like I have done some exercise after a ride, I don't get off in a state of physical exhaustion. I'll be able to use it to commute to work but not have to take a change of clothes. Sorry if this sounds a bit evangelical but I have been genuinely surprised by how much I am enjoying riding again.

Hi,

My first bike was a front wheel 500W hub motor kit from a shop in Albury. I have paired it up with a Lithiom Ion Phosphate (LifePo4) battery. I have put on 3800km in 10 months and lost 38kg in the process so it's a win win. Even at 500W (1300w peak) you still need to pedal to keep a good speed of 32 km/h.

I don't think 32 is too fast at all. I have my speed controller set to 32km/h instead of 45km/h because at those speeds my humble V brakes are not helpful. I get about 70km off my 36v 30Ah battery. In all that time I've had no problems, just ride and recharge. This is a home built kit, I just bought the kit.

My new e-bike is a 1200W chain driven kit (cyclone) that let's me use the rear gears. I've reached up to 72.2km/h on this, but when I go for rides with my girl friend she keeps to 30 km/h like me. 72 is it's maximum speed. We don't regulate cars my max speed, we regulate by a speed limit.

I have 2 friends that both have highly modified e-bike up to 2800w and can reach 60kmh in no time, and I'm with them, we will all happily continue to break the law until sensible legislation is put in place.

A throttle has many more positions than off or full, same as a car. But while the oil companys bribe our government, nothing will change.

From personal experience, once you get over 55km/h that's when it starts to get scary. But I choose to limit my speed to 31-32km/h to help my fitness and extend my range.

Thanks
E-bike rider in Canberra for 10 months.

Oh, the main reason for converting my bike to electric was showering at work in the morning after a 20km ride. Then after a long day at work I dreaded the long ride home all up hill. I started driving the car but parking was $5 a day and it was full by 7:30am.

Fast forward to today and parking is now $7/day, petrol is more, roadworks makes the drive 40 minutes. I now ride to work 40minutes with only a raised temp. No need to shower.

Money saved (est. Over 10 months)
Parking: $7/day - $1,400
Petrol: $50/week - $2,000
Total: 3,400 roughly

Bike kit: $400
Lifepo4 battery $550
Power/charge: 4c/day = $8

Saved : $2,442

So I'm pretty happy with that. It's not about saving money for me, it's about enjoying my life. I'd rather break the law by riding my e-bike to work enjoying the outdoors rather than being stuck in traffic listening to talkback radio. Plus after a heavy day of laboring work where I can barely lift my leg, I can just throw my leg over my eBike and twist the throttle and get home.

I've been commuting by bicycle (weather permitting) for 3 years.

The decision to go back to a bicycle was a daunting one, mainly because I wasn't in great shape.
At over 50 I found myself needing to address health issues from poor life choices and bad habits.
So I went to my local bike store an came away with a mid-priced range hybrid city bike.
It was the bike of my dreams.

The sad thing back then was that I was so unfit that I couldn't ride my bike for any serious distance, particularly due the the hills near where I live.
Not to be put off, I bought a training frame.
This helped to some extent, but it was back to the gym trying to get in shape.
Still no cycling and SWMBO suggested that maybe the bike was a bad idea and I should sell it!!!
Ohmygod NO!!!!
I loved my bike I just wanted to ride it. I'm sure I could - if it wasn't for those hills.
The breakthrough came when a friend assured me the hills in his area were as difficult as mine, and told me about a pedal-assisted electric bike.
WOW - I thought.
Hours of internet research later I finally converted my bike with a Cyclone conversion - 200 watt electric motor.
(I had a bicycle store specialising in eBikes do it for me. I didn't have the time, expertise or facilities, but I'm reliably told that it can be done at home.)
Image
It was fantastic.
It had provided the help I needed to get on the road.
I was a convert to eBikes.

I'm on my second bike now.
A better hybrid bike, (the bike of my dreams 2) and a much improved conversion an eLation 200 w - better torque for hill climbing and lighter battery.
Image
During my rides I'm pedalling the bicycle all of the time except when coasting. The 200 watt motor is combined with my input and gives me the power necessary for the conditions.
I can do a round trip to Sydney CBD which is over 50km from where I live, easily on a single charge with the battery still having more to give.
I cycle 16km each way to work travelling towards Homebush.

The electric bike has enabled me to become an active cyclist in hilly terrains and gives assistance to ensure I complete a journey.
This technology has opened up cycling to me and provides an opportunity for exercise and enjoying the world. I ride each day and substitute my bicycle for my car whenever I can.
With the extra power I can easily conquer the hills around where I live and with a good set of panniers it gives me the added benefit of completing my shopping and visiting friends.
Needless to say, I'm fitter, have lost weight and have all the benefits that regular exercise brings.

On the Southern Freeway PSP yesterday I spotted a tandem with an electric front hub motor. The thing was flying along, I estimate at least 45kph.

Perhaps some time in the future I'd be into an electric-assist cargo bike. I have an xtracycle at the moment which is great but it is hard to get it up hills loaded. The thing already weighs 30kg, so I'm weary of adding more weight as it will be harder to handle when I'm just trying to get it into and out of the house.

for Cargo work, I like the BoB trailer, when I'm finished I just unhook it, and voila, no extra weight.

just got rid of my one-wheeled trailer... the xtracycle is much nicer to handle loaded. The xtra can also take human passengers, extra bikes etc. The only limit is my legs :O
