Default Re: Gas or Electric, Which is most Popular?

The motor bicycling map only shows members who volunteered to pin their location, the reality is that that map would be 10x populated if it was mandatory to sign up to the site.

Electric bikes will sell themselves when the batteries come down in cost so that they don't equate to 50+ percent of the cost of the bike. When the price of a 1Kw motor kit plus battery pack is less than $300, then people will not need to be convinced to purchase them, and they will begin to replace the position that engine kits currently fill.

Comparing electric to gas is like comparing apples to oranges at this point in time, since in their current form they appeal to different market segments, rider expectations, and type pf use. When electrics can meet all design objectives of power AND range AND cost AND ease of use, they will be a more appealing product than a gas conversion to most people who don't have a preference for gas engine feel and sound.

One thing that continues to be a concern with electric appliances using lithium batteries is the ever present risk of fire. Amazon pulled most of the hover boards from their site due to batteries causing fire hazards in many cases. These battery packs are very similar to those sold for bikes. LiFePO4 batteries are way safer than Lithium polymer batteries, but still contain flammable electrolyte which can catch fire or explode if too much current flows through the pack and it overheats or has dielectric breakdown. It's still advisable to change batteries under supervision in a fire proof container, and be careful not to over charge or discharge, as well as limiting peak current draw to the recommended C rating of the battery for max cycles. This can mean that you need a high capacity pack with a high C rating for a high power motor, which can be done with a high Ah battery or by using high voltages like 72v or more and limiting peak current. The drawback being cost, the pack that I want to use to power a bike of at least 1500w peak would cost at least $600 for the cheapest pack with BMS shipped directly from overseas. I wish the reality was more fortunate, but I remain patient for the eventuality that battery technology catches up to the rest of the electric bike and make them viable for everyone, on any budget.
