best electric bike for heavy rider image

k5mudder

I want it mainly for the street with a little dirt riding. I want to have a dual sport bike but I don't want the xr650 because its just too big and heavy. I know the 450`s are a lot peppier and easier to handle which seems more fun for the street. So out of the crf450x and crf450r, which would be more ideal?

Answer
The bikes have the same cc's.

The CRF 250X has a Bore and Stroke of 78mm X 52.2mm
The CRF 250R has a Bore and Stroke of 76.8mm X 53.8mm
This means the 250R has a longer stroke, which means that it will have more torque.

The CRF 250X is running a carb, the CRF 250R is running fuel injection.

The CRF 250X is running 12.9:1 compression.
The CRF 250R is running 13.2:1 compression.
This means the CRF 250R will produce more power.

The CRF 250X is running larger intake and exhaust valves than the CRF250R, which means it can move more air/fuel through the engine.
This means CRF 250X engine will breath better high higher rpms.

The CRF250X has a wide ratio five speed transmission.
The CRF250R has a close ration five speed transmission.
This means the CRF250X would be better for long straightaways and road use.

The CRF250X has electric and kick start.

Both have over 12" of travel front and rear.

The CRF250X has an 18" rear wheel.
The CRF250R has an 19" rear wheel.
This means that you will have more options with the 18" rear wheel.

The CRF250X has a 1.9 gallon fuel tank
The CRF250R has a 1.5 gallon fuel tank
This means the CRF250R has more fuel so that it can travel farther because of more fuel.

The CRF250X is made to be a cross country racer. This means that it would work better for a dual sport bike.

Which commute bicycle is best for me?

Tara

I am looking for a bicycle for a commute to work of about 8-10 miles and would consider an electric model. Can anyone offer any specific models? There is so much out there to choose from. The area where I live can be fairly hilly, so higher number of speeds would be best, and I'm wondering how often there would have to be battery replacement on an electric bike. Any help would be appreciated, preferably from personal experience, but speculation from an experienced rider would also help. Thanks.

Answer
You can get a good electric assist bicycle - for a few THOUSAND dollars. http://www.trekbikes.com/us/en/collections/electric_assist/models/ Or...you could take the initiative to get a nice entry level "performance hybrid" with the gears to pull hills under your own power. And this bike may just come factory equipped with fenders & a rear rack for under $400! You will get & stay fit. Electric assist bicycles make you fat & lazy. What if the charge in the battery runs low or out at the wrong time & in the wrong place? Then you are faced pedaling an extremely heavy bike home under your own power. See these two links...
